Really need some advice with this one, ds who is 17 mths has a nasty habit of head banging floors, doors etc if things not going his way. The biggest worry of all is that I am 38/40 pregnant and 2 nite he headbutted my 2 week old niece because I was nursing her. He hit her such a crack I thought he had fractured her skull, obviously I am concerned as how best to deal with this especially as ds no.2 is due in a couple of weeks. He does tend to headbutt other children as well as me
