My son is 10, I was 42 when he was born, he has a 14 year old brother who is a great brother, caring and sensitive. My 10 year old is really comical, adorable, smart, but has awful anger issues. He is not from a split home, his father and I are married and live together. He also has Klinefelter's Syndrome. This was diagnosed through a pre-natal amnio test (due to my age). The Klinefelter's isn't obvious by any means, though he's pre-puberty. I don't know if his anger/behavioral issues has to do with that, and even if it does, I still need advice. If he's mad, he gets violent, hits things (has broken 2 windows), beat his bicycle with a hammer because he was "mad at Grandma", screams at the top of his lungs, and I'm at a loss. He gets in trouble at school, and I can't say many of the kids his age want to play with him for any length of time. I've tried many avenues, trying to talk him out of being mad, sometimes I say, "Change your face from that mean look to a nice look and we'll talk" and he usually smiles and changes his mood. But no matter what we try, he gets angry and lashes out before anyone can stop it. It's embarrasing, I don't feel like I can get anyone to "watch" him, because no one wants to deal with his behavior. Like I said, he's adorable, he's funny and he's smart, I'm looking for any advice to know how to change his behavior.
