You will know the plan is working when his grades start improving. Work together with your husband. Sit down with him alone when he is not angry. Let him know the name calling and anger is not helping to solve the problem. Let him know you feel caught in the middle.

These aren t skills we re born with, and everyone makes mistakes in the process of learning them. The ultimate responsibility lies with your son.
