Parents often describe their ADHD child's lying as manipulative. In most cases, it isn't.
A child with weak inhibitory control answers before they've decided what to say. The denial is out of their mouth before any "should I lie?" calculation has happened.
And for a child with strong rejection sensitivity, the flinch is bigger, because being caught doesn't just mean trouble. It means exposure, and exposure feels unbearable.
That changes what works for a parent.
The instinct is to confront: "Why did you your sister's maltesers?!" But cornering a rejection-sensitive child triggers a reflex denial - so switching to a flat statement ("I can see you ate them") corners them just as hard. The problem was never the wording. It's that you've made honesty the path that leads straight into shame.
So take the shame out of the moment, not the consequence.
Separate the two out loud. Start with what they're not in trouble for: "You're not in trouble for being hungry, and you're really not in trouble for telling me the truth." Then the part that stays firm: "But those maltesers were your sister's, they weren't yours to take. So you'll pay her back out of your pocket money."
The child still faces a consequence. What they don't face is rejection. Rejection sensitivity is triggered by feeling cast out, not by being held to account. So you can be firm about the maltesers and unmistakably clear that you're disappointed but haven’t rejected them as a person.
That's the line most parents miss: warm on the child, firm on the behaviour.
None of this means lying goes unaddressed. It means addressing it should match what's actually driving it, which, for most ADHD kids, is impulse and shame, not calculation.
