My 4 yrs old is not listening to teachers, especially when he is in the class. He is active and loves to play games,cartoons,playing with other children etc.. But he doesn't concentrate when his teacher ask him to do to write or read,he doesn't want to sit with the teacher at-least for half an hour..He will simply sit and do something in his book or the table. When his teacher ask him to connect dots or write numbers he avoids it and do any other job and look other side. This behavior is disturbing other students of the class. Everyday his teacher is complaining about his behavior. I really don't know what to do? But when he is at home he will behave nicely, he will do homework very fast and whatever his mom and dad says. And he is very much attached to us. I don't know why he is misbehaving with others. So please tell me what to do??
