Well report it probably a bit strong, buy the playschool are monitoring his behaviour and just wandered if this has happened to anyone elses son.
I have been assured that its not because exceptional bad behaviour, in fact he is one of the best in the groups, they are just trying to keep his enthusiasm under control. for example if they are standing in line for sometime he jumps on the person infront and is easy excitable, at first I was not sure what they were getting, but the assure me they are preparing him for school.
