My oldest son "Bob" was diagnosed as being a child with ASD (Autism Spectrum Disorder) when he was about four years old. He showed many signs at an early age but like many other parents/caregivers, I wrote it off as he was delayed. One of the first school memories I have of him is when he was in preschool and the teachers had to duct tape his crayons. Bob was obsessed with peeling and picking items. He was peeling the paper off of his crayons and didn't focus on anything but that task until it was completed. He would pull the loose strings in the circle time carpet and the tiniest strings he could find on his clothes.
