My stepson is 9 years old also. At the end of October a boy at school told the rest of the kids at school that they could not be his friend. His grades went down and he started to be problematic at home (also on ADHD medication). After a huge blow up in our household about his behavior and a call from his prinicple he finally told us what was going on. We went to the prinicple's office the next morning to tell him what was going on. The prinicple talked to his teacher and the boys involved. It would have been better to head the whole situation off earlier and did not have to talk to the parents. The sooner the situation is dealt with the better. Good luck and god bless.
