We are currently evaluating my son (5 yo in KG) for Asperger's. He's been diagnosed with Sensory Integration Disorder (SID). His KG teacher is having a really hard time with him in school. He is constantly touching other kids (particularly boys) and getting too far into other people's personal space. She's trying all kinds of different redirection techniques without much help. He does this at home too, but we can easily tell him to stop or redirect him. But, in a room with 20 kids, he's too overstimulated and can't control it. KG teacher asked me if it would help him to have something else in his hands all the time. At home, he's always carrying a car or plane around. If not, his hands are in his mouth or on something. At school...he's got to keep his hands to himself. Any tips on what sort of thing he could carry with him at school? Can't send a toy with him.
