It is the parents' job to help their children learn how to deal with difficulties in life.
...Because they are exposed to and observe high-conflict adults, children and youth of all ages model destructive behaviors at school. Parents are role models for their children and abusive behavior can be inter-generational. This direct link to bullying increases the pressure for separating parents to learn ways to reduce conflict in their interactions with each other.
If you are a separating parent who learns your child is bullying at school, here are some specific tips to help you remedy the situation:
If your separation includes high levels of conflict with the other parent, find ways to reduce the conflict.
Help your child learn productive ways to express anger.
Clarify that even though the family is going through a lot of changes, you will not tolerate bullying or mean-spirited behavior of any kind. Believe it or not, children of all ages find security in clearly set limits.
Stay actively involved in your child's school activities.
Make your child a priority during the separation.
