Misbehaving in preschool

Our child is having behavioural problems at preschool. He becomes defiant when there's a change in the schedule or when the teacher asks him to switch activities. He wants to do things his own way and in his own time. How do we change his behaviour?

We'd suggest that the solution to your problem may need to begin at home. It's rare for a child who is normally compliant and well-behaved with his or her parents to become defiant and uncooperative in other settings. You didn't mention anything about your son's attitudes and behaviour around the house, but is it possible that he's just as defiant with you as he is with his teachers?
