A compilation of research from distinguished contributors in the United States, the United Kingdom, and Germany is presented in Postpartum Depression and Child Development. The editors, Lynne Murray and Peter J. Cooper, founded the Winnicott research unit in the department of psychiatry at the University of Cambridge and later at the University of Reading. The book is divided into five sections, with a foreword by Eugene Paykel and an afterword by Michael Rutter. Individually and together, the sections succeed in the goal of illuminating the darkness of postpartum depression and its complex sequelae in infancy and early childhood.
