Hi....I am not a parent, however I have good friend, who is a single mom of a very smart four year old boy. He is all boy, meaning he likes the rough and tough play, sports, all the boy stuff, spider man etc. Her concern is that in karate and t ball, he lets other cut in front and that kind of thing. He doesn't stick up for himself. I have noticed he has a very sweet spirit and cares about others which is great, but can anyone give some advice on helping a child learn balance between being kind and not getting pushed around???? Thank you...Heidi
