What is actually happening in the brain and nervous system of a PDA child when they are in a threat state? In this episode I sit down with Dr. Amy Arnsten, a neuroscientist at Yale, to get the most scientifically grounded answer I have ever had to that question.
We talk about the prefrontal cortex and the amygdala: what they do, how stress flips the brain from thoughtful and regulated to reactive and survival-focused, and why that flip can happen so rapidly. Dr. Arnsten also explains the role of dopamine and norepinephrine under stress, how cortisol amplifies those pathways, and why perceived control, not actual control, is what determines whether the prefrontal cortex stays online.
For those of us who have watched our children go through exposure-based treatments that seemed to make things worse rather than better, Dr. Arnsten offers a neuroscience framework for understanding sensitization and why repetition without safety can deepen threat pathways rather than extinguish them. She also explains how guanfacine works and why it may be helpful for PDA children and teens with a heightened threat response.
This is one of the most validating conversations I have recorded. I hope it gives you more compassion, more language, and a clearer picture of the biology underneath what you are living.

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 TakeawaysParadigm Shift Program — My signature program where the autonomy, demand lowering, and holiday navigation frameworks described in this episode are practiced as daily skills, with live coaching to help families apply them across every season of the year.

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
Paradigm Shift Program — My signature program where the theory of change described in this episode is practiced as an embodied skill across twelve weeks, with live coaching to help parents move from understanding the logic to applying it consistently in daily life.

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 TakeawaysDr. Alex Klein — Dr. Klein's website, where families and clinicians can learn more about his work supporting neurodivergent children, teens, and their families.
Paradigm Shift Program — My signature program where the advocacy framework, cost-benefit decision making, and the full accommodation toolkit Dr. Klein and I discuss in this episode are taught across twelve weeks of live coaching.

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 TakeawaysParadigm Shift Program — My signature program where the five-characteristic framework, cost-benefit decision making, the PLATO advocacy tool, and the full unschooling and accommodation approach described in this episode are taught across twelve weeks of live coaching.

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 TakeawaysRestoring Childhood — Dr. Gray's new book, available September 15, on why the youth mental health crisis predates social media and what actually needs to change for children to thrive.
Paradigm Shift Program — My signature program where the autonomy-supportive approach Dr. Gray describes is practiced as a daily skill, alongside cost-benefit decision making and the full accommodation framework.

What if a school had no mandatory classes, no grades, no homework, and no age segregation, and instead gave students a genuine vote in how the school runs? That is the Sudbury Democratic model, and it offers some real benefits for PDA children and teens.
In this episode I speak with Bryer Newlin, a youth rights and disability justice advocate, self-identified PDA adult, and staff member at Clearwater School in Seattle. We talk about what it means to experience autonomy as a bodily sense, how equalizing behavior is translated in a school setting rather than punished, why clean up can be a can't rather than a won't, and what the misconception of no rules really misses about how democratic schools actually work.
Key TakeawaysClearwater School — The Seattle-area Sudbury Democratic School where Bryer works, offering a student-directed, democratic learning environment for families in Washington state and available for consultation for out-of-state families as well.

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 TakeawaysParadigm Shift Program — My signature program where the full accommodation framework, including the autonomy and nervous system safety tools introduced in this presentation, are practiced live across twelve weeks of coaching.

What does it look like when a school actually meets a PDA child where they are, without behavior charts, compliance goals, or pressure to perform? In this episode I speak with three remarkable people: Melissa Petro, a cultural journalist and mother of an eight-year-old PDA son who fought for years to secure him a free and appropriate education; Chela Crane, Executive Director of Otto Specht School in New York, where Melissa's son Oscar is now thriving; and Suchi Swift, a Waldorf teacher at Otto Specht who works directly with Oscar.
Together we cover Oscar's journey from expulsion at preschool and eight months of homeschooling through burnout, to the slow, non-linear process of rebuilding trust and regulation at a school that does not measure success through compliance. We also talk about what public school teachers can take from this model, what one family went through in fighting for private school placement, and what it actually looks like when a PDA child gets back into their thinking brain consistently and begins to lead their own learning.
Key TakeawaysOtto Specht School Website — The school featured in this episode, offering a Waldorf-based, neuro-affirming educational program for children who learn differently in New York. Families and educators are welcome to reach out directly.
Otto Specht School on Instagram — Follow Otto Specht School for ongoing content about their educational model, student life, and approach to neurodivergent learners.
