Your child melts down over mistakes, won't try things unless they can do them perfectly
Modelling mistakes yourself, patience, process-focused praise
Perfectionism in autistic and ADHD children is often anxiety-driven — they've learned that mistakes lead to unpredictable reactions, or their rigid thinking makes errors feel catastrophic. Modelling your own mistakes and celebrating brave attempts gradually teaches that imperfection is safe and survivable.
Can appear from age 4 onwards. Often intensifies around ages 7-10 as academic demands increase and self-comparison with peers begins.
A parent started deliberately making small mistakes in front of their child — misspelling a word, burning the toast — and narrating their response: 'Oops! Oh well, I'll try again.' Their child, who used to rip up any drawing that wasn't perfect, started saying 'it's OK, it's just a mistake' to themselves.
