The Invisible Forces at Work
In the previous chapter, I told stories about the people who entered my son’s life and either found their way to him or didn’t. Now I want to explain what’s happening under the hood.
This chapter is about my son’s neurology. His operating system. You can’t brute force your way through it by imposing your ideas on him. It’s his nature. And just like nature, it is best navigated on its own terms. Hopefully you’ll understand by the end of this chapter how ignoring this creates real harm and why.
Every autistic individual has a capacity that fills and drains. Most only see it after it’s empty. By the end of this chapter you will understand that mechanism. But first, we’re going to talk about all the steps in between.
Let’s take a walk through his neurology. I’m going to start by trying to explain what baseline looks like for my son through the lens of his neurology. The version of him you will probably never get to see.
My son spends 99.9% of his time at home either performing or doing what is called
Stimming.
This is short for “self-stimulatory behavior.” These are repetitive movements, sounds, or fidgets like hand-flapping, rocking, pacing, or humming that help him manage his emotions, calm his nervous system, or express joy. It is a natural way of self-regulating. There’s rarely a single moment in his home life that is not spent with some form of it. I do it too. And although we do it together sometimes, an act I call co-stimming, most of the time it’s really difficult for me because of the sensory overload. So I wear headphones at home 99% of the time.
I’ve only observed two cases in which my son stops stimming. If it reduces or stops at home, it is a sign that my son’s nervous system is overloaded. Additionally, before or during a growth spurt he will get quiet for a few days. Sometimes almost zen-like. As enjoyable as these calm days can be, I’ve learned to maintain a low sensory profile. Because what follows is often a very difficult phase. The second case where my son goes quiet is
Masking.
Masking is the conscious or unconscious hiding of autistic traits in order to blend in with neurotypical (non-autistic) societal expectations. This might look like forcing eye contact, mimicking other people’s body language, or suppressing the urge to stim. It requires a massive amount of energy and often leads to severe exhaustion or burnout. My son learned early, probably by watching other children, that stimming is not “normal.” As soon as anyone comes through the door, or we leave the house, he instantly stops. Sometimes I try to initiate it, and when I do, he looks at me with a mean face. If I continue anyway, he will say: Papa stops. Kasey is the only human other than me that has ever seen my son in his natural state. Ever. Sit with that a bit. Because it’s no small thing. This means my son spends 100% of his time outside of the house masking.
Caretakers must realize that when they are interacting with an autistic child, they are almost always already in a coping mode. It is best to keep this in mind before first contact. The autistic mask is worn for safety. I always use this example to help neurotypical people better empathize with high masking autistics:
Imagine you are in a witness protection program. You wear an actual mask in order to conceal your identity in public. You feel okay as long as you move through the world without anyone noticing. As long as everyone is doing their thing, not paying special attention to you, you feel relatively safe. But you’re anxious. On high alert. Now imagine you walk into a store. The space is smaller, people are closer. They look at you passing by. This would make you more anxious. Now imagine you at the cash register to pay. Now you have to not only wear the mask, but embody the role. And this makes you even more anxious. Then you leave the store. Suddenly someone approaches you, smiling, well-intended, and speaks to you. They just want to give you a compliment on your hair. That’s all. And suddenly your anxiety shoots through the roof. Your heart starts racing. You play along but the only thing you want is for the interaction to be over. When it finally is, your heart slows down. But you are now more anxious than you were before it. This holds until you get back home and are able to remove the mask.
This is the masking experience for any autistic, and even most non-autistics. The highest amplitude of anxiety is experienced in active engagement. Not just with strangers, but with anyone on the other side of the mask. The unmasked version of my son is so drastically different from the masked version. Try to imagine what it must be like for him to spend hours in this state.
My son’s main way of expressing himself is speech. He tried to mimic words before his body could even form them. Before he could even crawl. He’s not just talkative, he’s something else. While many autistic children are nonverbal, he is what is called
Hyperverbal.
In the context of autism, it isn’t just “talking a lot”; it often involves a flow of speech that is very fast, difficult to interrupt, or highly focused on a specific topic. It can be a way of processing thoughts out loud or a response to social anxiety.
This is important because speech is my son’s window into his soul. If he’s not speaking, the curtains are closed. Much of what can be read and understood about him is in the way he uses speech. He started speaking at an unusually young age. The way his very first words were expressed is still his main way of communicating, stimming, and masking. The mechanism behind all three is the same. It’s called
Scripting and Echolalia.
The repetition of words, phrases, or sounds previously heard. So much of what can be read about my son is in the way he does it. He might quote from a book to answer social demands. Caretakers might mistake this for conversation, try to interpret what he’s trying to say, and get it wrong. My son recognizes this and interprets it as distance, which has a tendency to compound his anxiety.
He might cycle through different phrases from books, cartoons, and conversations while playing. This is a good sign. If a caretaker tries to perform active bonding through play and conversation, he might start repeating the same phrase over and over again. What he is communicating is he doesn’t know how to respond. If the caretaker continues to try and converse on this basis, this only compounds anxiety and eventually burns bridges. Many never see or feel this happen. They imagine bond building while at the same time my son is invisibly growing an anxious aversion to the person. It’s these kinds of dynamics that turn into sleep sabotage weeks later.
The best way to respond to this is not by interpreting his words conversationally. Don’t try to layer on top of them, but echo the exact phrase back to him. That’s all. Just repeat whatever he says. You just met him. You have no idea what he reads, no idea what he watches, and you have no idea what he’s talking about. But you don’t have to.
Echoing and mirroring will do a lot of things at once. It will release the social pressure on him. It is bond building and coregulation at the same time. Instead of an invisible anxious aversion building up, you might find him trying to initiate mirroring games with you.
Tightly interlinked to echolalia is an expression called
Pronominal Reversal.
This is a well-documented feature in some children on the spectrum. My son mixes up first- and second-person pronouns. For example, he says “You’re hungry” when he means “I’m hungry.” He refers to himself as “you” and others as “I.” I regularly practice the game “I am me and you are you.” But it still hasn’t caught on. And it might take a while.
And here the same rules apply. Everyone interprets this the “wrong” way around and tries to converse with him based on it. It’s another subtle way to build that distance while imagining a bond. I’ve seen it over and over again. My son feels drawn to someone and as the interaction deepens, he starts to shut down and distance himself. He interprets your inability to read him as distance, not bonding. And if you continue to pursue him, it only deepens his anxiety and his aversion to you.
I experienced this during a photo shoot. The boyfriend of a model was sitting on the couch. My son sat next to him and started connecting. It was a beautiful sight. So much so that the model was distracted by it. But then he started responding to the reversal. I noticed how quiet my son got. I tried to explain to him the phenomenon of pronominal reversal. But he immediately dismissed it. Not in a bad way, he dismissed it in a way meant to tell me that it’s okay that he’s like this. But he didn’t understand, and the conditions didn’t leave me the space to explain how he should conduct himself. So I just let it run. At some point my son just got up and went back into his room to play alone.
And this is where so many people get it wrong. They follow him. This is exactly the wrong move. My son’s body proximity means everything. The boyfriend respectfully asked me if he could go into my son’s room and play with him. I kindly said no. My son was retreating, I was letting him. An awkward silence filled the room. Only the clicks of my camera and my son’s playing filled the airwaves.
The last link in this chain is connected to the main source of his scripting and echolalia material. He has been able to read since he was two years old. The term for this is
Hyperlexia.
This is a strong, early, and often self-taught ability to read that is significantly ahead of what is expected for a person’s age. While a child with hyperlexia might decode complex words and read fluently at a very young age, they may simultaneously struggle with oral language or understanding the actual meaning behind the text they are reading. This also applies to my son. He recognizes words like pictures. He can pronounce many complex words many adults struggle with. But he doesn’t know what many basic words actually mean that other children his age know. This might lead to overestimating his ability to comprehend speech.
But the thing you need to realize is that most of what he says isn’t conversation at all. It is scripting, echolalia, sometimes masking, and often stimming. That doesn’t mean it’s not communication, it is. The worst thing you can do is interpret it as conversation. When in doubt, echo it back to him. Not performatively, he can feel that. Don’t always add conversation to it, just be present with it. It will change the interaction in ways you couldn’t have anticipated. Caretakers often feel as if they have to “do something.” You don’t. Saying and doing nothing at all is more often than not exactly what my son wants.
If my son repeats the same phrase again and again during close-proximity engagement, this might be a sign that the interaction is being interpreted as social pressure. His other nonverbal cues will speak the same language. As I said before, proximity is everything. If he moves away, even if just an inch, do the same. And reduce your input.
This repetitive scripting has a name. And again, the way he does it gives me insight into his nervous system. It is called
Looping.
This is basically getting “stuck” in a repetitive cycle of thoughts, words, and/or actions. This can be a soothing mechanism to deal with anxiety, or it can happen when he gets locked into a specific, intense train of thought that is difficult to break away from. My son loops all day long. It drives me insane. I try to announce everything that comes next in order to help him transition better. But sometimes he will get stuck in a loop when he’s excited about it. For example, if I say we’re going to a place he likes, he will follow me everywhere while I’m trying to get ready and repeat “we’re going to x.” He will do it anxiously with a worried look on his face, not registering all the signals of preparation. It’s very difficult to get him out of it. I have to give him something of equal or greater excitement to distract him at this point. But if I get ready first, start packing first, then tell him, he is able to register everything that is happening as part of the process.
So many things my son does are repetitive. That’s just the shape of autism. Looping is the more severe mode, and it is unmistakable. More often than not, the thing he is looping about is not the problem at all. Sometimes it comes after many layers of
Sensory overload
has been traversed without anyone noticing. This is when the brain receives more input than it can process. This is more often than not invisible and misunderstood in caretaking environments. I’ve heard caretakers blame it on the other children, the noise, and busyness time and time again. Although these are contributing factors, what they almost never see is their own contribution.
I regularly subject my son to intense sensory environments. Sometimes for the sole purpose of training his nervous system. He is extremely skilled at self-regulating such situations. The things that make the biggest contribution to my son’s sensory overload are close-proximity social interactions with the caretakers. Even when first contact goes well. It is the traditional active bonding techniques practiced even by the most aware and gentle of caretakers that compound stress. More often than not, he is tolerating your presence, not enjoying it.
Sometimes some kind of outburst or looping will follow. The immediate reaction is often for caretakers to satisfy the thing he is looping about. This is more often than not exactly the wrong move. If my son is falling and you react to the looping instead of responding to him, he will continue to fall. If he is very dysregulated, he will not be able to give an accurate self-report of his needs in that moment. It is one of the situations that can only be correctly interpreted by someone who has heeded everything I’ve written so far. Someone that has truly bonded with him and not just imagined it.
If my son is stuck in a loop, the correct response is often difficult to see. And I’ve been judged for it over and over again by neurotypical friends. Sometimes what he needs is complete disconnection from whatever situation he is in. This might trigger protest, crying, or even a huge
Meltdown.
An involuntary, physical response to overwhelming sensory or emotional stress. It is fundamentally different from a tantrum. A tantrum is behavior used to get a desired outcome; a meltdown is a total loss of behavioral control because the brain and body have reached their absolute limit for coping.
To say this is extremely rare is an understatement. The last one was described in The Kindergarten Part 2. And the time before that was three whole years ago. Before I understood everything in this chapter.
When my son has traversed a threshold of sensory overload, removing him from a situation or environment would trigger a meltdown. This is not a sign it was the wrong thing to do, exactly the opposite. My son does not respond this way when he’s okay. As soon as he has enough distance from the situation, he would exit the loop and wrap his arms around me tightly. I was his anchor now. He would often immediately be able to articulate exactly what went wrong, when or where it happened. Sometimes it took a few minutes. This is the part those who judge me never got to see. And it is almost impossible to change hearts and minds by telling the story in retrospect.
My son has been taught to verbally express his feelings and maintain situational awareness connected to them. Although I can usually trust his self-report, his mask prevents him from communicating his needs to caretakers. My guess is the compounding mistrust in their ability to interpret his communication. He more often than not won’t say anything at all. And when caretakers ask him questions, he will either say yes to everything or just repeat back what they say. A conversation at home often yields a wholly different outcome.
I urge caretakers not only to follow everything in this chapter as best they can, but also to trust the process. Giving my son space to come and engage on his own will give him the same space to come to you when he needs you the most. He’s solution-oriented. If he has a problem, he will always look for the first person that can help him solve it most efficiently. If he doesn’t have that person, he won’t come at all. This becomes a recurring theme: he will simply solve the problem at home by sabotaging his sleep so he doesn’t have to go back.
But my son also has subtle cries for help that are devoid of clear signals. There are situations that require you to read him better than he can read himself. The most often occurring scenarios can be categorized under two terms.
Autistic Inertia.
This refers to the difficulty autistic individuals have with starting, stopping, or changing a state of being. Like the physical concept of inertia, once my son is “in motion,” focused on a task, or “at rest” in a specific environment or posture, it takes a tremendous amount of external or internal force to change that state. Sudden or unannounced changes can lead to significant stress. I handle this by announcing an upcoming change or using a timer on my iPhone. He always gets to hit the alarm stop button himself, which initiates the mode change all by itself. A secondary effect of this is called
Interoceptive Hyposensitivity.
Interoception is our “eighth sense.” The internal sense that tells us if we are hungry, thirsty, need the bathroom, or are in pain. In many autistic individuals, this sense is “muted.” When my son is dysregulated or in a state of inertia, he can lose the ability to feel those internal signals. He might stay in wet clothes or sit on a numb limb because the brain is simply not “registering” the discomfort signal. It isn’t that he doesn’t care; it’s that the message is getting lost in the noise of his dysregulation. He might even insist on staying in a situation he knows is not good for him and would naturally avoid.
This is another one I’ve seen time and time again. Caretakers telling me my son is okay, and said he wanted x. Or said he didn’t want to stop y, or leave z. At home, he tells me how horrible it was. I’ve fallen for it myself time and time again. I’ve come to recognize his nonverbal cues that tell me he needs a mode change.
These two might express themselves as contentment in play.
If my son is in an unfamiliar environment and plays for hours in the same position, he’s not okay. He never does this. Any time he has, it was in a situation where he was connected to an object like a toy while coping with one or more overwhelming factors.
If you read his cues you can anticipate this before it happens. If he is dysregulated or in sensory overload, as soon as he finds that one thing, he won’t move until you move him. Most of the time I will do some form of sensory cooldown instead of letting him zone out with toys. If this is what he needs, he will never resist.
Other times I try to attract him to other activities. Because allowing him to zone out robs him of the self-regulation that comes with remaining in the discomfort of an unfamiliar place. Sometimes that play scenario is like him leaving the environment, retreating into himself. When he finally exits, for his nervous system, it is like he was never there. He never gets a chance to acclimate or even regulate.
I taught him to observe and name things when he’s overwhelmed. He’s adopted this as his own form of self-regulation. When you hear him say “this is x,” “that person is doing y,” don’t make the mistake of turning the thing he names into the next activity or try to turn his words into any other kind of conversation. It is a special kind of scripting. Sit with it. If you recognize the pattern, just play the game with him. Name objects, say what someone is doing. Use few and simple words. This will help him process the environment and will significantly reduce his anxiety.
Like so many things in this chapter, recognizing how to respond to my son’s cues requires listening and slowness to respond. Especially while you’re getting to know him. It becomes intuitive after a while. But most caretakers never get there.
The next thing I want to describe is different from everything above. The terms so far have been states my son moves through. This one is the principle underneath all of them. It shapes how every other term in this chapter expresses itself. If autism is my son’s nervous system, this would be the programming language. A language I had to learn in order to not only stabilize my son’s fluctuating health, but unlock his heart. I cannot emphasize this enough. It is in everything he does and everything he is. It is called
PDA (Pathological Demand Avoidance)
Often referred to as a “persistent drive for autonomy,” this is an autism profile characterized by extreme, anxiety-driven resistance to everyday demands. It stems from a nervous system reaction to perceived threats to control, not defiance, requiring flexible, low-demand support strategies. PDA is not currently a standalone diagnosis in the DSM-5/ICD-10. It is understood as a profile within the autism spectrum.
It took me so long to understand this. And like most of the things in this chapter, I documented it and had conversations about it with his mother before I found the term. This is not “misbehaving.” Traditional behavior-based discipline like rewards or punishments does not work and often compounds anxiety. It is not “refusal.” He’s not being lazy or naughty; his brain perceives a severe loss of control, making compliance nearly impossible.
Any threat to my son’s autonomy is met with resistance. He has it down to an intricate science. And there are so many layers to it, I would have to write an entire essay on how it expresses itself. It is the only thing I don’t expect any caretaker to read clearly. It’s that deep. All they can do is yield to it by respecting his autonomy and everything I’ve written in this essay. If my son cannot enforce his autonomy in a situation, he will try to force it on whatever he can control. If that’s not enough, his last resort is to sabotage his sleep.
This is what is happening when caretakers practice active bonding before my son has chosen who he wants to bond with. Everything they are used to doing with other children is a violation to him. When my son wants to engage with someone he’s bonded with, he sends me away. He says: Papa goes now. My compliance is absolute. I don’t just move away, I move out of his sight.
One of our best kindergartens did everything right on first contact. At the time of writing, we are still in the process of vetting them. My son bloomed more than he ever has on a first visit. He didn’t just pick one caretaker, he engaged with all of them. And not only the caretakers, he engaged with the children. Something he has never done even on a third visit.
At some point he went from the garden into the kindergarten where he was met by another caretaker. I remained with the director while she gave me a tour. At some point I went into the kindergarten and found my son in the classic scenario: him playing on the floor while a caretaker actively engaged with him. I never got to speak with her about the mechanics of my son. I saw her actively shaping the interaction. So many words. And I heard her converse with my son without knowledge of the pronominal reversal. She got it wrong. But what got my attention is that I sat down in close proximity to my son, and he didn’t send me away.
This was not an exception. When my son feels safe with a caretaker, he sends me away as an expression of his autonomy. In that moment, my presence would undermine it. If he doesn’t feel safe, or he is tolerating the caretaker, my presence strengthens it. I still didn’t say anything. I usually don’t intervene unless what is happening is doing real harm. The caretaker did everything right. They clearly have experience with autistic children. The easiest thing is often the most difficult to understand: don’t engage, respond. Don’t lead, follow. I just observed. But I knew what was happening inside my son, and I anticipated signs would follow. They did.
When it was time to leave, I announced it and the caretaker put on a timer. I told him we would be leaving soon. The first sign was: no protest. Not even a facial expression. The second sign was, when he got up and the same children he had previously engaged with approached him, he panicked. He jumped up and down while flapping his hands. They didn’t even engage with him directly, they were just walking by. This was the wait-for-it moment I was anticipating. It was the tension and anxiety that had built up during the interaction with the caretaker.
Autonomy is not just a preference. It is wired into everything in this chapter. Masking is control. If I initiate co-stimming while he’s masking, I undermine his autonomy. Play is control. If you actively engage, offer, or add to the experience verbally, you undermine his autonomy. My presence is control. When he feels safe in an environment, he sends me away. If he sends me away and I don’t leave, I undermine his autonomy. When my son has an outburst or loops on an object, this is control. A reaction to compounding loss of autonomy.
Sleep sabotage is the final stage of control. It is what happens when many layers of autonomy have been violated.
Let’s take a breath.
By this point I wouldn’t be surprised if you’re feeling a bit overwhelmed. Believe me, I get it. I’m his father, I do this every day. You’ve just ingested years of experience and observation in minutes. That’s no small feat. But we’re not done yet. Take a pause if you need it.
Everything in this section was learned the hard way. Each term you read about was just a single layer to an onion I had to peel one by one because we lived the devastating consequences of what happened when they were invisible. Over and over again. You see, I was suddenly thrust into single parenthood when my son and his mother returned from a Mother Child Retreat. It was a hostile environment for both their nervous systems. His mother is also a diagnosed autistic. She never recovered and has been in the clinic ever since. I got my son as a child that had lost the ability to speak. A phenomenon known as
Skill Regression.
The temporary (or sometimes long-term) loss of abilities or skills that a person had previously mastered. But it didn’t stop there. He banged his head against the wall. He hit other children and had meltdowns multiple times a day, every single day. This sensitive, loving, bright and intelligent, hyperverbal young boy was unrecognizable. Both of them had been crushed to liquid by a system that wasn’t made for them. It took weeks to restore him to something that appeared anything less than broken on the surface. Months to stabilize. And years to heal.
The lesson I learned was that it didn’t start in the clinic. It started at home. In our ignorance. Every sensory overloaded scenario we subjected him to without knowing he needed things like sensory cooldowns. His whole life had been a yoyo of peaks and exhaustion with long recoveries. And it was secretly compounded at the kindergarten every single day. By a staff that reported him as “okay,” every single day. After I put my son back together, it took less than a week of kindergarten for him to lose his speech again. He was not okay there. He was never okay there. Not a single day.
It took weeks to put it all together. Thankfully the kindergarten participated in every bit of my inquiry and experimentation. We mutually came to the conclusion that they were ill equipped to facilitate a child with his needs. This is where the whole journey of this essay even begins. But before we even got there, I had to see my child in something I didn’t recognize even though I’d experienced it myself.
Autistic Burnout.
A state of physical, mental, and emotional exhaustion caused by the long-term strain of navigating a world designed for neurotypical people. It is much deeper and more debilitating than the “burnout” people typically feel after a busy week at work. I myself experienced it as unexplainable pain, just being alive. It literally hurt to exist. Sensory overload can cause me actual, literal physical pain for a moment. Autistic burnout felt like the same, but as a continuous state. I recognized it in the way he interacted with the world. He responded to life the way someone would avoid putting weight on a wounded foot. Aversions to sound, light, any kind of sensory input. I didn’t yet know he was autistic. I just intuitively did everything for him I did for myself when I experienced my autistic burnout. And he recovered.
This is where we came from. And all of this is what it took to understand my son. Not a single layer of the onion but all of them at the same time. It wasn’t a linear process. It oscillated at first. Then stabilized. I experimented and adjusted, sensitized myself to the oscillations until I found the corridor in which he can survive without collapse. I also learned that internal factors also impact his nervous system like growth spurts. And external factors like the sleep adjustments during spring forward and fall back time changes. Through all of this I still don’t overprotect him. Quite the opposite. I regularly and intentionally subject him to conditions that train him to self regulate and teach his nervous system how to adjust. Never once have I ever let him slip into skill regression again.
If you had met my son three years before this essay, you would have experienced him as a troubled child. His entire life since he was a baby constantly oscillated between some kind of crisis and recovery. He’s been stable for two years straight without a single episode of eczema, meltdown, skill regression, or burnout other than the Kindergarten Part 2 story. And the occasional very minor issue during growth spurts. The journey I’ve been through taught me something I’ve come to recognize and apply to myself. Even his mother started applying these principles, which has strengthened her recovery journey. And this is where I would like to hear from you. Because I strongly believe this applies to many autistics. They are two principles that work together. The first one is called,
The Reservoir.
Every autistic person has a reservoir. Think of it as a finite amount of capacity the nervous system holds at any given time. Every nervous system impact event drains it. Every overwhelming sensory experience, every social demand that exceeds the person’s conditions, every moment of masking, sleep quality, and more. As long as the reservoir is above a certain threshold, the person looks fine. They appear functional.
This is where most get it wrong.
They see a child who appears to be managing, but two weeks in, the child collapses and everyone is shocked. That’s because everything they got wrong was happening in the first 50% of the reservoir. The child was draining in real time, in front of them, and they couldn’t see it because the symptoms hadn’t started yet.
The symptoms don’t start until past the halfway point. And this is different for every child. It could be behavioral. Irritability, sleep disruption, scripting, looping, avoidance. Or physiological. Eczema, digestive issues, startle responses, regression. Below a certain threshold, autistic burnout isn’t far away. A state that can take weeks or months to recover from. By the time the child is showing symptoms, the reservoir is already critically low. You are not catching the problem. You are watching the consequences of a problem that started long before you noticed. The most dangerous part about this: the longer an autistic stays in a low reservoir state, the more intense the burnout and the longer the recovery takes. Even more dangerous than that, I’ve seen many autistics continue in this state without it being recognized until they are repeatedly misdiagnosed with alternating forms of psychosis. They go through doctor after doctor, each one codifying their own interpretation of what is wrong according to the DSM-5. Adults and children alike.
And here is the mistake I see repeated everywhere. I’ve even done it to myself time and time again. As soon as the symptoms go away, the child goes back into the environment that caused them. The adults assume the child has recovered because the visible signs have stopped. But the reservoir is still not full. It has just climbed above the threshold where symptoms are visible. The child is back at 40%, maybe 50%. And the cycle begins again. Each time with less capacity, each time with faster collapse.
This entire journey taught me to read my child at 10%, at 20%. Before the symptoms even start.
The Corridor.
This is probably the most essential piece of information I’ve learned in my experience with my son, and even his mother. It was the piece of the puzzle that solved the yoyo effect in my son’s stability. I didn’t read this in a textbook. I watched it happen. And then I found the science that explained what I had already seen. I had to find a way to explain what I was observing to his mother. So I drew a graphic and called it the corridor.

In Polyvagal Theory this is known as the window of tolerance. A range of sensory and emotional stimulation within which the nervous system can stay regulated. Within that corridor, the reservoir can fill overnight. He sleeps, recovers, and wakes up with capacity.
Above the corridor is
hyperarousal.
Chronic nervous system over-activation. The nervous system is activated past the point where sleep alone can repair it. The child is distressed and dysregulated. A “fight-or-flight” response that stays active without present triggers. It causes physical and emotional symptoms, including intense anxiety, insomnia, hypervigilance, irritability, and startle responses. I recognize the signs. And I’ve come to know which scenarios lead to them. Every story in chapter one between me and caretakers, babysitters, practitioners, and family was me trying to explain exactly this. What people need to realize is that a high masking autistic is already at the top of the corridor when they meet them. Masking alone is a high arousal state. This is why a child visiting a kindergarten for the first time can be pushed into hyperarousal with even the smallest of well-intended gestures.
What most parents and caretakers need to understand is what happens when hyperarousal continues without sufficient recovery. The nervous system doesn’t stay elevated forever. It drops. Not back into the corridor. Below it, into
hypoarousal.
This is the most dangerous state, because it looks like the opposite of a problem.
The child is quiet, compliant, and still. To every adult in the room, it looks like the child has settled. Like the strategies are working. Like the storm has passed.
It hasn’t passed. It has gone underground. The child’s nervous system has shut down to conserve what little is left. This is not calm. This is collapse with a mask on. And what follows, when it finally surfaces, are the stories that parents tell in support groups with shaking hands. The worst meltdowns. The longest regressions. The moments that feel like they came out of nowhere but were building for weeks behind a face that looked fine.
What recovery looks like
Repeated hyperarousal events drain the reservoir. Once the reservoir is drained below a certain threshold, the child enters hypoarousal. The longer the child stays in hypoarousal, the longer the recovery and the higher the risk of autistic burnout. As intense or complicated as all of this might sound, it’s really not. The journey down the reservoir is marked with signs. Every child has their own. There are thin markers and thick markers. The thin markers are behaviors and patterns triggered by hyperarousal events. The thick markers are physiological patterns triggered by reservoir drain positions. The goal is to recognize the thin markers and respond to them before the thick ones manifest.
Once my son is outside of the corridor, he can only exit it with external help, or a lot of time within the corridor. In order to help him, I do what I call cooldowns. We have many forms and my son usually gets to pick his own. But all of them include closing all the shades and introducing dim warm lights.
Full body massage: a well-practiced mix of massage and acupressure.
Stomping: I hold my son in my arms, put on down-tempo music, and stomp hard to the rhythm.
Touch therapy: I put on classical music, lay him on my chest, and caress his back.
Water therapy: I hold my son in our rainfall shower tuned for big heavy droplets that hammer the skin on his back.
Sensation therapy: a series of alternating stimulations like squeezing limbs, tight hugs, slapping feet and hands.
The recurring phenomenon during these cooldowns is a child that has deep breath spasms over and over again. The kind you have after intense crying. A term known in psychology as the physiological sigh or double-inhale. An involuntary action that activates the parasympathetic system. The long, extended exhale following the double inhale is the critical part for relaxation. It stimulates the vagus nerve, which signals the parasympathetic nervous system (rest-and-digest) to activate, decreasing heart rate and lowering blood pressure.
Caretakers
Explaining this to caretakers is extremely difficult. I don’t expect caretakers to recognize the markers. But what I do expect is for them to listen when I explain it to them. But often they do not. At the very least, what my son needs is for caretakers to be honest about what happens in care. I’ve had them withhold when my son was hitting. A behavior that comes at the very bottom of the reservoir.
I’ve come to accept that even when it goes well, it’s going to take at least one collapse until they get it. That is if I’m lucky enough to find one that can accept the explanation at all. Because often, by the time a low reservoir becomes visible for them, it is already too late. The problem is, many parents don’t know how to read their own children. But even if they did, I’ve not had much luck getting caretakers to accept it even after I explain a collapse. My sons doctors and practitioners understand this. And they have helped me understand it even better. But I cannot seem to find childcare institutions who are able to even scratch the surface.
In the next chapter, I want to address caretakers directly.
