We are having anger / aggression issues with DS (3.2). He is being referred for speech and language therapy on the recommendation of his nursery director and also because I mentioned to her he was physically aggressive with his younger sibling at home and can often push other children around. His speech isn't terrible but it's not as good as others and there are certain sounds he cannot say. What I really want to sort is the behaviour and the suggestion is that if he can communicate better the aggression might stop. However he does have the vocabulary to say what's wrong so I'm not sure why he can't put it into practice. Any ideas?
