I was pretty sure something was different about him when he was very young. He had a funny walk and would fall a lot because he was fearless and would move too fast. He often seemed to be in his own head and I guess you could say he was quirky.
When he was a preschooler going in for a teeth cleaning, the hygienist was kept on her toes trying to clean his teeth because he was so active in his seat. By the third grade he could no longer be managed in a regular education setting! To be totally honest, I don’t think he was ever highly engaged in his preschool through second grade experience, but there were enough other distractions in those primary classrooms that his challenges could still be overlooked… or accommodated by teachers or volunteers.
