Ds is 2.10. He is starting to have much better language skills, and can express himself more. But in conflict situations, he either chooses, or I suspect resorts when language fails him, to hitting, scratching or biting. It is always when someone is trying to take his toy, or screaming or shouting at him-usually his sister or a younger child. It is not when he wants a toy or book from another child. Adults and older children tend to behave more sensitively to his needs and listen when he says he doesn't like something. I try to hover unobtrusively and intervene, but with a little baby this isn't always possible. He is old enough that there needs, I think, to be a consequence to his action. However, I also think it's fair to him to let him know that he wasn't wrong to dislike the behaviour of the other child, just in the way he reacted. When it's his sister, I point out to both why they were wrong and they both say sorry. And are taken away from the activity if necessary. I feel uncomfortable saying anything to the other child and it is the other parent's role to help their child to appropriate behaviour. But that sometimes leaves ds "in trouble" and the other child not-as physical aggression trumps all else in some books (mine too-but not all unacceptable behaviour is physical). I want him to feel understood, but also to learn that dealing with things physically is totally unacceptable. Ironically, He seems to have learnt to share, will give up a toy willingly when asked and he's had a turn and just can't cope when it's unfair ie he's having a turn and someone wants to force him out.
