Judy Dunn, a leading international authority on childhood development, provides a beautifully written account of children's early friendships. Drawing on evidence from studies on both sides of the Atlantic, it considers the nature and significance of such relationships for children's development and well-being. The book concludes by drawing out the practical implications of research for parents, teachers and those who care for children, including how to manage friendships at different developmental stages, how to help children with friendship difficulties, and what to do about 'trouble-making' friendships and bullying.
