How can I know if my six year old son is bipolar.He behaves at school, is very smart ,he behaves with everybody but me ,but he can love me now then turn around and hate me ,if I ask him to do something like his homework,he'll say that's why I don't love you!he is not spoiled but changes moods a lot, but they don't last long, he can be mad and next minute he is OK.Alot of my close friends do think he has a problem ,I am so confused I also think he has a problem.
