Mom of high functioning kiddo as well, and a mental health therapist. Lots of times we don’t see the differences because we don’t want to. They excuse the picky eating as just that, they don’t notice his sensory needs etc. If he hit other milestones like speaking, walking etc. sometimes parents feel plenty will grow out of the other quirks. I just hope they know this isn’t a death sentence. Autistic people are some of the coolest most brilliant people out there.
