I have tried not shouting...not spanking but my 4 year old continues to be aggressive with kids. Whenever he sees a kid his height or shorter,he will go hit him. Even when that child is not looking towards him. I have asked him why he is hitting but he looks down and keeps quiet. He is only child. But I have seen other single kids too and they do not behave like this. Is there any other parents here sailing or sailed in same boat? Otherwise he is an intelligent kid but short temperd. I have tried being patient since 3 days but he does not seem to be improving at all. Shall we take him for counselling?
