You would be surprised Hannah, quite a few children are very caring and would,if asked by a teacher, take your son under their wing at break times. Also the teacher could arrange a class assembly that celebrates' how children are different, and with your permission they could perhaps explain in terms understandable to 10 year olds, about your sons condition. Getting the class to understand your son will curb their curiosity as well as including him in the class as a valued member.
