Hi, I strongly suspect my son has sensory processing disorder but isn't diagnosed, basically because he gets by ok. He is very sound sensitive but at nearly 6 is now able to handle the hand dryers at school and the vacuum cleaner etc. When we are in public washrooms he covers his ears just in case someone else uses the hand dryers. He is in year 1 now and all I've heard from school is that he has trouble "listening" at times and settling down after breaks to sit calmly on the carpet. Though his year 1 teacher is saying that after no more than 2 reminders he will be fine. Anyway, to the subject of my post. Once a week he's got a team sport and he loves it. It is so frustrating for me to watch though because he gets so overstimulated that he has trouble listening to the coach, following directions, chews on things and also has hand and vocal stims. Basically he can't regulate himself. What can I do to calm him down? He's got about 10 minutes between school end and the sport where he gets changed into his PE kit. Would chewing gum help as heavy work for his mouth? Any other ideas?
