My son is 3yr 2mths old. He never listen to what we say and almost do opposite of that. He is very demanding. And very frequently switch to different demands. Like I want to watch TV after 10 min he says that I want see rhymes after few min ask for coloring. I am worried about him whether he is OK or hyperactive.or whether I am not able to handle him.at home he is quite but when we go out to market or at any relative place he misbehaves. This specially happens with me. If he is with someone else or at school there is no such problem. He is obedient to others.how to handleit?

Because he knows you will allow him to behave like this. He does it since you have allowed it to happen. I will guess you "give in" at some point to his demands, not just ignore his tantrums or give him a small swat on the rear and tell him to stop it.
