Friends broaden our children's horizons, share their joys and secrets, and accompany them on their journeys into ever wider worlds. But friends can also gossip and betray, tease and exclude. Children can cause untold suffering, not only for their peers but for parents as well. In this wise and insightful book, psychologist Michael Thompson, Ph.D., and children's book author Catherine O'Neill Grace, illuminate the crucial and often hidden role that friendship plays in the lives of children from birth through adolescence.Drawing on fascinating new research as well as their own extensive experience in schools, Thompson and Grace demonstrate that children's friendships begin early--in infancy--and run exceptionally deep in intensity and loyalty. As children grow, their friendships become more complex and layered but also more emotionally fraught, marked by both extraordinary intimacy and bewildering cruelty. As parents, we watch, and often live through vicariously, the tumult that our children experience as they encounter the "cool" crowd, shifting alliances, bullies, and disloyal best friends.Best Friends, Worst Enemies brings to life the drama of childhood relationships, guiding parents to a deeper understanding of the motives and meanings of social behavior. Here you will find penetrating discussions of the difference between friendship and popularity, how boys and girls deal in unique ways with intimacy and commitment, whether all kids need a best friend, why cliques form and what you can do about them.Filled with anecdotes that ring amazingly true to life, Best Friends, Worst Enemies probes the magic and the heartbreak that all children experience with their friends. Parents, teachers, counselors--indeed anyone who cares about children--will find this an eye-opening and wonderfully affirming book.
