K.S.
I am happy to answer questions for you and let you share your trials and tribulations with this rocky and still misunderstood (especially by peds) disorder. My son was diagnosed when he was 3.5 thanks to a lucky set of circumstances. I happened to be in a moms group at the time and one of the other kids had SPD. And then my son's preschool teacher mentioned that we might want to have him evaluated because of how he was struggling in the classroom with body control, noise avoidance, and other reaction well outside the norm. I read "The Out-of-Sync Child" which gave me greater understanding. I also had resistance from his ped for a referral but I had enough information backing up my request including a recommendation from the Early Childhood evaluator that he relented.
OT is wonderful. I observed every session and let the therapist know that I was interested in learning as much as I could. Starting school would have been miserable if I had not had a good understanding of how DS responds in group settings and could give his teachers a heads up. Second grade is more of a challenge because while the teacher gives lip service to his needs I am not sure she really understands that he experiences the classroom differently. She sees that he handles a given situation fine one day and then the next he is reacting differently and she thinks he is just trying to get out of his work.
