If you've ever watched your autistic child melt down in the supermarket, or seen your ADHD teenager shut down completely the moment you ask them to do homework, or wondered why your PDA child seems to refuse absolutely everything on some days and not others, you've probably asked yourself some version of the same question:
Why are they doing this?
And if you're being honest, in those exhausted, overwhelmed moments, the question might sometimes come with a darker edge: Why are they doing this to me?
That question, the blame-shaped version, is completely human. It's where most of us start. But it's also, gently, the wrong question. And in this post, I want to offer you a different one.
All Behaviour Has a Purpose
Here is one of the most important things that behavioural science has taught us, and one I come back to again and again in my work with families, SENCos, and school professionals:
All behaviour has a function. Every single time.
Even when it looks random. Even when it seems designed to push every button you have. Even when it makes no sense to anyone in the room, including, sometimes, the child doing it.
Behaviour that looks challenging is almost always a child's best available attempt to:
- Escape or avoid something that feels too hard, too overwhelming, or too much
- Access something they want or need
- Connect with you to get your attention, your reassurance, your presence
- Cope with something happening inside their body or nervous system that they don't yet have the words or skills to express
That last one is particularly important for neurodivergent children. For autistic children, ADHD children, and children with a PDA (Pathological Demand Avoidance) profile, the sensory, emotional, and regulatory demands of everyday life are often significantly higher than they appear from the outside. What looks like "overreacting to a small thing" is frequently a nervous system that has already been working incredibly hard and has simply reached its limit.
The behaviour isn't the problem. The behaviour is the message.
The Blame Trap, And Why We All Fall Into It
When a child's behaviour is intense, frequent, or disruptive, the instinct, for parents and school professionals alike, is to focus on stopping it. To find the consequence that will make it go away. To ask: how do I get them to stop doing this?
This approach is understandable. And it's also insufficient on its own. Because if we only ever focus on stopping a behaviour without understanding what's driving it, we miss the message entirely. We take away the child's only available way of communicating something important, and we haven't given them anything better to use instead.
This is the blame trap. When we frame challenging behaviour as a child being defiant, manipulative, attention-seeking, or deliberately difficult, we're making assumptions about intent that most neurodivergent children, particularly autistic children, PDA children, and children with ADHD, simply cannot support. Their behaviour is not strategic. It's functional. It's the output of a nervous system doing exactly what it's designed to do: seek safety, seek connection, and avoid pain.
The moment we stop asking "why are they doing this to me?" and start asking "what is this behaviour trying to tell me?" everything changes.
The Detective Mindset: Curiosity Over Blame
This is the shift I work on with every family and every school team I support. I call it moving from a blame mindset to a detective mindset.
A good detective doesn't walk into a scene having already decided who's guilty. They gather evidence. They look for patterns. They stay curious, open, and non-judgmental, even when what they find is complicated or uncomfortable.
Applied to behaviour, this means asking different questions:
- What happened just before this? What was the child being asked to do, or stop doing?
- What was the sensory environment like? Was it loud, bright, crowded, unpredictable?
- Had there been a transition, a change of plan, a shift between activities?
- How had they slept? Had they eaten? Were they already running on empty before this started?
- How much connection had they had that day? Were they coming home from a full day of masking at school?
These are the clues. And for neurodivergent children (autistic children, ADHD children, PDA children), these factors are not peripheral. They are often the entire story.
The behaviour at the end of the day wasn't caused by the shoes you asked them to take off. It was caused by eight hours of effort that had nowhere left to go.
What This Looks Like in Practice: Home and School
At home
Picture a 10-year-old, let's call her Amara, who has been masking all day at school. She's autistic, and school requires a level of social and sensory management that her neurotypical classmates don't experience in the same way. She gets home, drops her bag, and goes quiet on the sofa.
Her parent, who has also had a full day, comes over and says, "Come on, can you get changed? You've got swimming in an hour."
Amara explodes.
To an outside observer, and in that moment, to her exhausted parent, this looks disproportionate. Unreasonable. Perhaps even manipulative.
But look at the evidence. Amara's nervous system had been regulating itself all day. She came home with nothing left. The instruction (however reasonable) landed on an empty tank. Home is the one place she feels safe enough to let the armour come off. The meltdown isn't about swimming. It's about the weight of everything that came before it.
Understanding that doesn't make the moment easier in the short term. But it completely changes what you do next, and what you do before next time.
In school
For SENCos and school professionals, this detective mindset is equally essential. A student who refuses to enter the classroom is not being defiant for its own sake. A child who flips a chair when asked to start a task is not manipulating the situation. A teenager who shuts down and goes silent when given feedback is not being passive-aggressive.
They are all, in their own way, communicating something.
The PDA student who seems to reject every instruction, even ones they'd previously agreed to, is often experiencing demand as a threat to their sense of safety and autonomy. The response isn't defiance. It's a nervous system in survival mode.
The ADHD student who can't sit still, can't start a task, can't wait, isn't choosing "not to try". They are experiencing a neurological difference in executive function that makes those things genuinely harder, not just inconvenient.
Understanding the function of the behaviour (the why behind it) is what allows us to intervene effectively and compassionately. Not just to manage the moment, but to actually support the child.
The Four Questions Every Behaviour Detective Asks
Whether you're a parent navigating a meltdown at home or a SENCO supporting a student in crisis, these four questions are your starting point:
1. What was this behaviour trying to get or avoid? Was it an escape from something overwhelming? Access to something needed? A bid for connection? A way of coping with a body that feels out of control?
2. What was happening just before? Not just the immediate trigger, but the broader context: the sleep, the sensory environment, the demands of the day, the state of the relationship.
3. What is this child trying to communicate? If they had the words, the skills, and the regulation to tell you, what would they say?
4. What could I teach instead? Once we understand the function, we can begin building skills that serve the same purpose but in a way that works better for everyone. Asking for a break instead of running away. Using a signal instead of shouting. Knowing that saying "I need five minutes" will be respected.
This Is the Heart of The Calm Circle
This detective mindset (curiosity over blame, understanding over reaction) is the foundation of everything I'm building inside The Calm Circle.
The Calm Circle is a monthly membership community for parents and school professionals who want to go deeper into understanding behaviour. Not in a jargon-heavy, textbook way, but in a real, practical, human way that actually helps in the moments that matter.
Each month, members receive:
- A video training grounded in behavioural science and neuroaffirming practice, translated into language that actually makes sense
- A companion resource or worksheet to use straight away, with the whole family or in school
- A community of parents and professionals working toward the same thing, side by side, not in separate corners
In Month 1, we are diving into exactly what we've discussed in this post. The Meltdown Detective Worksheet, one of our member resources, walks parents and professionals through six areas of investigation: triggers, sensory factors, transitions, sleep and hunger, demands, and connection needs. It's a practical, curiosity-first tool for turning behaviour analysis into understanding rather than blame.
Because your child isn't giving you a hard time. They're having a hard time. And there's always a reason.
Join Us as a Founding Member
The Calm Circle is brand new, and I am welcoming the very first 30 founding members with a special launch discount.
If you are a parent of a neurodivergent child (autistic, ADHD, PDA profile), or simply a child who experiences the world more intensely than most, this community is for you.
If you are a school professional such as a SENCo, a teaching assistant, a family support worker, or a pastoral lead who wants evidence-based, trauma-informed, neuroaffirming approaches to behaviour support, this community is for you.
Use code CALMFOUNDER30 at checkout to access your founding member discount.
Spots are limited to the first 30 members. Once they're gone, the founding rate goes with them.

A Final Word
Behaviour is communication. It always has been. The meltdown, the refusal, the shutdown, the aggression, the running away, none of it is random, and none of it is personal.
It is a child, your child, or the child in your classroom, doing the very best they can with the nervous system, the skills, and the resources they have available in that moment.
Your job isn't to stop the behaviour. Your job is to understand the message.
And you don't have to figure that out alone.
Come and join the circle. I'd love to have you there. 💛
