Written as part of a training pack for practitioners working in child care and child protection, and bringing together leading figures from a range of disciplines, this important text shows how the latest child development theories can be applied to professionals' working practice. Considering theories of development throughout the lifespan from the early years through to adolescence, and transitions to adulthood, this resource is essential reading for a range of professionals including social workers, teachers, and health and mental health professionals. The authors build up an integrated picture of the developing world of the child, looking at genetic and biological influences alongside individual psychological, interpersonal, familial, educational and wider community domains. The final part of the book looks specifically at issues for practice, including chapters on communicating with children exercising professional judgment, and planning, interventions and outcomes in child care.
