Look for signs. Many children will not complain about being bullied at school, but rather will express a desire, often sudden, to avoid certain school activities such as riding the bus, or even to avoid school altogether. This can take the form of psychosomatic illness or dropping out of previously favored activities.
Take your child's concerns about bullying seriously. Especially in the wake of recent events, the need to prevent school violence must be paramount.
Assess the severity of the situation. If your child has been physically harmed or threatened with physical harm, notify the school immediately and insist that it take immediate action to protect your child from violence.
Work with your child to brainstorm ways to deal with a less severe bullying situation directly, and help him make a plan. The more you can empower your children to manage their own affairs, the greater their self-esteem will become.
Explain the dynamics of bullying to your child. Help him understand that bullying comes from the bully's low self-esteem; that is, a bully can only feel big by making others feel small.
Bolster your child's confidence. Despite their behavior, bullies are basically cowards, and gravitate toward easy marks. Encourage your child not to react to a bully's taunts, enroll him in a martial arts class, or otherwise make your child a less attractive target.
Keep a close eye on the situation. If things don't improve, or if your child begins to express concerns about his personal safety, don't hesitate to contact the school and get a resolution to the problem.
