Really though, what was that about? I don’t know is a valid answer. It communicates very clearly that the child cannot answer your question, and therefore maybe needs more help understanding the question/situation. Why do you try and push them to give an answer they don’t have? That stresses them out and it makes them feel like they’re being punished for not knowing something.

i thought i was the only one with an “i don’t know” problem because my parents made it seem it was the strangest and also most horrible thing in the world. i genuinely didn’t know and they got angry and that only blocked my thoughts more which meant i didn’t know the answer to anything else.

Also “I don’t know” is a commonly used sentence for children with ADHD/Autism. We DON’T know why we can’t do our homework. We DON’T know why we can’t eat certain foods sometimes. We DON’T know why we forgot to do a chore. It’s really distressing when you genuinely don’t know and people think you’re just lying or indifferent
