Throwback: 5 Ways to Recognize Pathological Demand Avoidance at School | Ep. 179
At Peace Parents PodcastShow Notes
This episode is a throwback to one of the most popular episodes in the history of this podcast, originally recorded as a live presentation I gave in 2022 at the Miami Sudbury Democratic School. I am releasing it again during September, a month I am dedicating to school and education content, because I keep hearing from teachers, therapists, and parents who are still looking for language to explain what they are seeing in the classroom. In this presentation I walk through the nervous system mechanism underlying PDA, the two most common paths PDA children take through school systems, and five observable characteristics that often appear regardless of whether a child is more externalized or internalized, age, or a formal diagnosis. Key Takeaways
Why Seventy Percent of PDA Children Cannot Access Any School: Two Paths | 00:03:49 The first path is a child who appears completely fine at school, does not qualify for an IEP or a 504, and whose teachers and administrators do not see what the parents are describing at home. But things are escalating at home, basic needs are being impacted, and the parents eventually pull the child from school feeling like no one believes them. The second path is a child whose high social communication skills lead professionals to call them high functioning, and when the behavioral expression of the disability appears, they are labeled as a defiant behavioral problem rather than a child with a nervous system disability. Both paths end in the same place: outside the school system.
The First Observable Characteristic: Equalizing Behavior | 00:13:26 Equalizing is what the body does when the nervous system has perceived a loss of autonomy and is trying to get back to a place of safety and equality. In a classroom it can look like reflexively touching something after being told not to, changing the rules of an activity, starting a worksheet in the middle, writing words backwards, walking away, putting a head down, or reducing meaningful speech. In a home it can look like targeting a sibling, knocking things over, or saying stop talking every time a parent speaks. What matters most is the adult response in that moment.
The Second and Third Characteristics: Masking and Undivided Attention | 00:18:08 Masking in PDA takes two forms: the learned social imitation most people understand, and what I call autonomic nervous system masking, where a child is experiencing full fight, flight or freeze internally while appearing calm externally. This is the primary reason PDA goes unrecognized and why parents are disbelieved: the child can look completely typical everywhere except at home, where they feel safe enough for the threat response to surface. The third characteristic is the need for a safe nervous system, meaning these children often cannot engage independently without a co-regulator nearby. My son needed us to draw what was in his brain for months, sitting next to him in an undivided way, before he could return to drawing himself.
The Fourth Characteristic: The Cumulative Nature of Nervous System Activation | 00:25:17 The ABC framework of antecedent, behavior, consequence does not apply to PDA because the actual causal moment is not the thing that happened right before the meltdown. It is the ten things that happened across the past day, week, or month, each of which registered a small loss of autonomy, building until a small trigger tips the child over. In my son's Montessori school, when a hard moment happens, we never ask what happened right before. We ask what has been accumulating.
Why Viewing PDA as a Nervous System Disability Changes Everything About Accommodation | 00:00:00 The most important shift I can offer any teacher, therapist, or parent is to put on the nervous system and autonomy lens first, before the sensory lens, before the social communication lens, and before the behavioral lens. When we understand that a child moving toward the campfire after being told to stay back, or refusing to eat t

Halloween is exciting. It is also activating. And if your child is in burnout, near their threshold, or simply wired in a way that makes novelty and sensory overload feel threatening rather than fun, even a holiday you love can become a source of dread for the whole family. In this episode I share five tips for navigating Halloween with a PDA child or teen, drawn from seven years of doing it imperfectly in my own home. I cover what to do if your child cannot access the holiday at all this year, how to think about autonomy and demand lowering as two distinct accommodations, why traditions still count even when they look like chaos, and why letting go of please and thank you on the doorstep may actually be the most effective thing you do all night. Key Takeaways
Why do accommodations like lowering demands, providing autonomy, and using declarative language actually work for PDA children and teens over the long term? And why do so many parents, therapists, and teachers get stuck applying them even when they understand the concept? In this episode, an excerpt from a live workshop I taught in 2024, I walk through what I call the theory of change for PDA: the logic that explains why these accommodations shift things at a nervous system level. I cover the two most common places where people get stuck, how to tell the difference between an accommodation and a reward, and why lowering demands alone is necessary but not sufficient for the transformation families are working toward. Key Takeaways
It is back to school season here in the US, and for most families raising PDA children and teens, that means navigating one of the most structurally activating environments their child will ever encounter. I am back with Dr. Alex Klein, clinical psychologist, to talk through what we are each seeing this fall and what we have learned over years of working with and being parents of neurodivergent children. In this episode we cover how to understand PDA as it plays out in school, why masking is real and why schools often do not believe parents, how to communicate about a PDA child's needs without leading with a label that gets dismissed, and the highest impact accommodations Dr. Klein and I have each found to be worth fighting for. We also talk honestly about what happens when schools are not allies and what families can do when the onus falls almost entirely on the parent. Key Takeaways
Should my PDA child stay in the public school system, move to a private school, or homeschool? There is no single answer, and this episode is not going to give you one. What it is going to give you is a framework for making the decision that fits your child, your constraints, and this specific season of your family. In this episode I walk through all five characteristics of PDA as they play out in a school or home setting, then move into the three schooling scenarios I see families navigate most: staying in the public school system and advocating for accommodations, finding a private school that is structurally more aligned with a PDA nervous system, and pulling your child out entirely to unschool, deschool, or homeschool. For each one I share what to watch for, what has worked for the families I have coached, and how to use the cost-benefit framework to make and hold a decision even when it is hard. Key Takeaways
Why are so many children and teens struggling with anxiety, depression, and school refusal right now? And why are so many of them PDA? I have been carrying these questions for years, and Dr. Peter Gray's new book Restoring Childhood gave me a framework I did not have before. Dr. Peter Gray is a research professor of psychology and neuroscience at Boston College, founder of the nonprofit Let Grow, and author of Free to Learn and, just published this month, Restoring Childhood, How to Set Kids Free in the Age of Anxiety. In this episode we talk about what play actually is and why it matters for development, why the evidence does not support that screens and social media are the primary driver of the youth mental health crisis, and what has actually been happening to children's autonomy and mental health since the 1950s. We also talk about his own son, who he believes would have been identified as PDA, and how that son changed the entire trajectory of Dr. Gray's research and writing. Key Takeaways
