Has anybody got any suggestions to deal with a son who at nearly 4 is still biting when angry. I thought he would have grown out of it by now and I keep reading things that if by the age of 3 your child is still biting there is a problem! I think this is a bit extreme but has anybody got any ideas to help. He is at nursery and went through of a phase about 4 months ago of being very aggresive and hitting/scratching and biting but his behaviour improved alot after lots of talks and some threats (from his father) but nows seem to have reverted to his previous misbehaviour. I would love to hear any suggestions - please!!!
