Thanks for your comments. I have spoken to his teacher who hasn't seen any signs of conflict - though I imagine most of them happen when she isn't around (lunch,recess).
There actually is no way to spend lunch recess away from the group (must eat together in class and must go to the schoolyard).
You're right - I remember very well the emotions of that age and how deeply things can hurt. This is what makes it difficult to insist that he go to school. I know he must but I really feel how much he doesn't want to. Being a very empathetic parent makes things both easier and more difficult.
