lizzieb I can't understand why so many children are being diagnosed as having ADHD and being prescribed Ritalin. I think it's worth exploring whether there are other factors that might be influencing his hyperactivity. I always think it's better not to start taking a drug unless it's absolutely necessary.
All children can be naughty at times and quite often children these days have more challenges to deal with (smaller houses/less space to play at home, blended families, etc.). You say he is reasonably well behaved when he is with you - and that you restrict his time on the computer. Is he playing games on the computer at his home? Computer games can get people very wound up and on edge, particularly if they're played for a long time and not interspersed with other activities.
Is he getting enough fresh air, outdoor play (to release physical energy) and plenty of sleep? Is there plenty of "quiet" time at home - or is the TV on constantly in the background or on too loud?
You say he's witnessed violence in the past, so his being a "handful" at school might be related to that. Has there been any input from a child psychologist or, for instance, any offers of play therapy?
As petra said, there are some good books out there - it might be worth having a look in the library.
This weather is getting me down. Is it May or March?
