Inspired by The Science of ADHD by Chris Chandler
A child who won’t start their homework. A student who won’t stop talking in class. A teenager who won’t remember their PE kit.
From the outside, it looks like a choice. And so we respond accordingly: “They just don’t care.” “They’re not even trying.” “They could do it if they wanted to.”
But what if they can’t?
The difference changes everything.
What adults see
We see a child who appears to be choosing not to do what’s asked. The homework sits untouched. The instructions go in one ear and out the other. The same mistakes happen day after day, despite reminders, consequences, and conversations. And it’s natural — human, even — to land on the assumption that they’re not trying hard enough. That if they just cared more, things would be different.
But that assumption is where so many of us get stuck.
What’s really happening
ADHD affects the brain’s executive functions — the systems that control starting, stopping, remembering, and regulating behaviour. When these systems aren’t working as expected, a child can’t do what’s being asked — even when they want to.
They forgot — not because they don’t care.
They can’t start — not because they’re lazy.
They react — not because they’re defiant.
The brain’s management system is working differently. And no amount of wanting to do better can override wiring that isn’t cooperating.
The “won’t” trap
This is where things can go really wrong — for everyone.
When we assume a child won’t, we respond with consequences, frustration, and pressure. We take things away. We lecture. We push harder. And sometimes it works for a moment, which reinforces the belief that the problem was effort all along.
But if the truth is they can’t, those responses don’t fix the problem — they just make the child feel broken. Shame builds. Confidence drops. They stop trying because “what’s the point?” The relationship suffers on both sides — at home and at school.
The “won’t” trap doesn’t just miss the mark. It causes harm in the exact places where connection matters most.
The “can’t” shift
When we understand it’s can’t, everything changes.
We stop punishing and start problem-solving. We stop blaming and start supporting. The child goes from feeling broken to feeling understood.
What it looks like in practice:
Scaffolding instead of consequences.
Curiosity instead of frustration.
Connection instead of conflict.
It doesn’t mean there are no expectations. It means we build the bridge to help them get there, rather than standing on the other side wondering why they won’t cross.
What to say instead
The words we use carry more weight than we think — especially for a child who already knows they’re struggling.
Instead of “Why won’t you just do it?” try: “What’s making this hard?”
Instead of “You need to try harder” try: “Let’s figure out what would help.”
Small shifts in language create big shifts in trust. These kids already know they’re struggling. What they need isn’t another reminder of what’s going wrong. What they need is someone on their side.
Why this matters
The kids who hear “why won’t you?” the most are usually the ones trying the hardest.
They’re not giving you a hard time. They’re having a hard time.
When you swap “won’t” for “can’t,” you don’t lower the bar. You build a bridge to help them reach it.
Every child wants to do well. When they can’t, they need us to believe that — even when it’s hard to see. 🤍
