This eloquent book presents an empirically supported treatment that engages parents as the most powerful agents of their young children's healthy development. Child--parent psychotherapy promotes the child's emotional health and builds the parent's capacity to nurture and protect, particularly when stress and trauma have disrupted the quality of the parent--child relationship. The book provides a comprehensive theoretical framework together with practical strategies for combining play, developmental guidance, trauma-focused interventions, and concrete assistance with problems of living. Filled with evocative, "how-to-do-it" examples, it is grounded in extensive clinical experience and important research on early development, attachment, neurobiology, and trauma. This book will be invaluable to practitioners working with infants and young children and their caregivers, including clinical psychologists, psychiatrists, social workers, and counselors. It may also serve as a supplemental text in graduate-level courses.
