Girls often engage in a form of bullying called "relational aggression". Learning to establish healthy boundaries is important. This can be part of resilience. American Psychological Association (APA) has information on many aspects of bullying. APA also offers many children's books on topics such as school related issues, self-esteem, relationships: Magination Press

Books such as Odd Girl Out and Queen Bees and Wannabees have been helping parents and girls understand relational aggression for several years. There is even a book on recognizing and dealing with Queen Bee Moms and Kingpin Dads.
