My 9 yr old son has recently started having quite frequent temper outbursts, not only at home, but at school too. He cries, shouts, screams, kicks and throws things. Most of the time he is a well-behaved, thoughtful, funny, bright boy. He hates being teased though and he hates perceived injustice and these things seem to really set him off. He also hates being told he's done something wrong. I'm worried that his friends at school will start to avoid him because of his unpredictability. He knows his behaviour isn't acceptable, but doesn't know how to manage it. I don't want him repressing his anger but would like to give him some tools for dealing with it more constructively. Any ideas anyone?
