Their body is always moving and they can't make it stop
ADHD child behaviour
What to do right now
The fidgeting, the running, the climbing, the bouncing. Their body is generating the stimulation their brain needs to maintain baseline arousal. Sitting still costs them cognitive energy that they need for thinking. Movement is regulation, not misbehaviour. Give them a wobble cushion, a fidget, permission to stand. They are more focused when moving than when forced to be still.
What your brain just did
Your body
They are bouncing, tapping, spinning, climbing. Their body is in constant motion. Asking them to stop produces a brief pause followed by more movement. They are not choosing to be disruptive.
Your brain
The ADHD motor system is under-stimulated at baseline. Movement generates proprioceptive and vestibular input that increases arousal to a functional level. Sitting still deprives the brain of the input it needs to think. They are actually less focused when still.
What this did
Accommodate the movement rather than suppressing it. Wobble cushions, standing desks, fidget tools, movement breaks. They learn better, regulate better, and feel better when movement is permitted. Stillness is the demand, not the goal.
What your child is experiencing
Their body
Their body needs to move the way other children need to breathe. The movement is not optional for them. Stopping it costs cognitive energy that they need for everything else.
Their brain
Motor output generates proprioceptive and vestibular input that the ADHD brain needs to function. Movement is self-regulation. Forced stillness removes a regulation tool and makes focus, attention, and emotional control harder, not easier.
What they need
Let them move. Wobble cushion, standing option, fidget tool, movement breaks. They are better at everything when their body is allowed to do what it needs. The stillness expectation is the mismatch, not the movement.
