I also want to thank you for going to the extra mile for this kid. As a parent of a difficult child that can act up in the classroom it is very meaningful to see that you care. I would like to suggest one thing, the boy may understand fully how much his behavior is different then the other kids but not be able to control it. There isn't much of a pay-off to let your peers see that kind of behavior and the reaction from his peers that you describe is one of my fears for my son. My child is only 8 and so far the class has adapted to his outbursts. I imagine the kids will take a cue from how you deal with it so I would try to be low keyed about it in the classroom. I know my son's outbursts scare the teachers in the beginning of the year but they also adjust as the year progresses. I know I would want to know if my son were being teased by the kids in school for the outbursts, other then that I don't know what you can do.
