My 5 year old son, seems to be displaying a lot of anger towards his schoolfriends in the playground.  Firstly, he is very large for his age, and when he pushes or hits, he does it very hard.  Academically, he is brilliant, quite advanced.   The problem occurs when he is out in the playground, he tries to boss other children around, and when he doesn't get his own way, he hits and kicks them.  When the teacher tries to pull him away, he is uncontrollable, and kicks out at his teacher, who otherwise he has a lot of respect for.   On the other side of the coin, he is a very loving and caring child, and rushes to help if someone has fallen over and hurt themselves.  The school are having difficulty in handling him, he's only been at school for 8 weeks so far, and they are already talking about me picking him up, so he can spend his lunchbreaks at home.   This problem is an ongoing one, he had problems at nursery too.  If another child had a toy he had previously been playing with, he would get into a blind panic, shouting THAT'S MINE, THAT'S MINE and he would storm over and snatch it from the child.  Many of the children in his school are scared of him.  It was said once that he is emotionally immature.  I don't know what to think.  I'm at the end of my tether.  Do you have any suggestions?   Will he grow out of it?  He'll be five next month.
