I have a son who is almost 10. He has always been an exceptionally well behaved boy, but recently his behaviour is changing. He is pinching things such as money on window sills at friends houses, food from other peoples lunch boxes. He is bored with anything we do or suggest and is lying to us. I think moodiness and feeling hard done by could be partly down to hormones. He is angellic at school, has lots of friends who we've had over this holiday. Too be honest I'm not sure how to handle the situation without making it worse. Anyone else in a similar situation?
