They keep saying they are bored and expecting me to fix it
ADHD child behaviour
What to do right now
They are bored and it is your problem. 'I am bored' is not a statement. It is a request for stimulation that their brain cannot generate internally. Do not list twenty activities. Give them two choices. Better: give them a physical task. The boredom is neurological discomfort, not a failure of imagination. A movement challenge, a building project, or a timed race meets the need without you becoming the entertainment.
What your brain just did
Your body
Your nervous system is activated. Cortisol and adrenaline are influencing how you think and react right now. This is physiology, not a character flaw.
Your brain
The ADHD prefrontal cortex provides less reliable braking between feeling and action. The gap between trigger and response is neurologically shorter than in a neurotypical brain.
What this did
What happened makes sense when you understand how your brain is wired. The reaction isn't the problem to solve. The conditions that led to it are.
What your child is experiencing
Their body
They are understimulated and uncomfortable. The boredom is not optional. It is a neurological state that feels physically unpleasant.
Their brain
ADHD baseline arousal is lower than neurotypical. When stimulation drops below threshold, the discomfort drives stimulation-seeking behaviour. They are not being lazy or unimaginative. Their brain is asking for input it cannot generate internally.
What they need
Movement, novelty, or challenge. Not a list of suggestions. Two choices or a physical task. The boredom resolves when the stimulation meets the threshold, not when they 'decide to do something.'
