Listen. If a young person reports a bullying incident to you, either as a target or a bystander, act immediately. Your child needs to know that you can and will help.

Stay aware. Keep the family computer in a central location where you can easily monitor it.
Be supportive. Don't under estimate what your child is going through. Listen to your child and try to understand the impact the bullying is having on them, and assure them that you are on their side.
