hi , my son 3 1/2 y , got his diganosis yesterday , we were kinda expecting it , but im still shocked, he gets all the support just now as he has global development delay also ,I thought he was doing great at his special needs nurery but in there report he is regessing with his social skills , shouts at the other kids when they touch him or pushes them awy if to close, doesnt understand facial expressions, hes had a lot off assesments in nursery and at the development center, atleast now i can explain to family members as to why he wont go near them and ignores everyone . just glad its over and we finaly have answers for all his behavoirs ,
