Ask your child to describe the bullying. Find out whether the bully has called him names, used physical force or touched him inappropriately. Ask him how the other children on the bus responded and how he handled being picked on. Ensure him that the bullying was not his fault and that you will do everything you can to stop it from happening again.
Encourage your child to board the bus with a friend and to sit in the front. A bully may not be so eager to pick on him if he has a friend by his side and sits near the bus driver. Do not encourage him to use violence to deal with a bully. Instead, tell him to remain calm and speak to the bully in a firm voice. Instruct him to simply tell the bully to stop, then walk away.
Help him think of ways to respond to a bully's remarks that will diffuse the situation. Pretend you are the bully and come up with different scenarios for your child to respond to. As he practices his comebacks, he will develop more confidence and responding to his bully will come more naturally.
Talk to your child's school principal if the bullying does not stop. Tell her how the bully has been harassing your child and that you want it to stop immediately. If the bully has hurt your child physically, talk to the principal about whether the police should become involved.
