6 yr old son very aggressive

[bklynmom02]

I am at my wits end. Over the last few months my son (will be 6 in a few days) has been aggressivly hitting his  4 yr old brother, so hard it worrys my sitter. He also verbally threatens my sitter ( I will put a bullet in your head), he has said similar things to kids in school. He is generally fine and controllable however has a mind of his own. Academically he is better off then most of his peers. He are changing schools , so in the fall its a new school. His last school was a complete joke with lack of strucutre, discipline, curriculum - -  a teacher who was over powered by her class of 8 KIDS!!. Just 8. Anyway his behavior is worrying us. Why threaten people, he has also cursed at kids in the park   - - sometimes more than your regular "bathroom talk" of stupid, idoit, etc. I have taken him to a therapist ( 3 of them) and they think nothing is wrong. They blame the school environment and his age. Boys just being boys. and my son trying to manipulate his surroundings. However his anger for a 6 yr old is troublesoom. He knows he is wrong, will apologize and say he wont do it again but he does. Pls help.

Could he have some jealousy issue about his little brother, this is very common also address what he watches on TV as the remark about put a bullett sounds copied, did you ask him about that ?That school does sound as if it could have been a problem aswell so at least he is moving to a new one and hopefully that willl be better ,when you hear him curse in the Park or at other children remove him from the Park so he wont be able to do it and tell him he wont go to the Park if he continues to do that,if he still does it after one warning be true to your word <NO Park, and dont go till he knows that is not permittable behavior.Does anyone call him stupid or an idiot, is the Babysitter good with him.Hopefully this will change at school but give him some Bounderys in the other places,Make sure he gets plenty of your attention aswell if he feels left out , and is there a Dad to play some Vigorous Guy Ballgames to let some energy out.
