My friend has shared with me over the past year that her son's aggressive behavior is causing a lot of problems not only with his school, but within her group of friends at playdates, etc. He has hit two of her friends' kids, he pushed a little girl down into gravel at school.. he's been sent home from school multiple times and most recently has been kicked out of a day camp because of his aggression. She has lost at least 2 friends because they refuse to be around her son with their kids. I see her once in a while, but usually only with her daughter when her son is in school. So, I haven't experienced him firsthand. We are not super close friends, but she does share this stuff and asks me for advice. A couple days ago, I told her that maybe she could consider counseling for him. I could tell she was put off by that and I haven't heard much from her since. Anyway... what would your advice be? I have a 4YO girl who definitely has some attitude problems, but I have never had to deal with any aggression or violent behavior (thank goodness).

Thank you in advance!
