This volume is the result of over twenty years of therapeutic interventions with families within the Tavistock Clinic's Under Fives Service. It describes in detail the process of understanding young children's communications and behavior and the dynamics of family relationships within the consulting room in a lively, accessible style. It covers common themes in work with young children such as disruptive, angry behavior, separation and sleep difficulties, and problems in the parent/couple relationship. This book is essential reading for all early years professionals hoping to gain a greater understanding of the technique, observational skills and theory which underlie a psychodynamic approach to work with the under fives.
