This book is an important practical resource for all professionals engaged with planning, implementing and evaluating multi-professional teamwork and practice in children's services. The first book to combine theoretical perspectives, research evidence from the 'real world' of children's services, and reflections on policy and practice in inter-agency services in England, this fully updated new edition retains its popular approach, while reflecting the numerous changes to policy, practice, and research. The book exemplifies what multi-professional work looks like in practice. It examines real dilemmas faced by professionals trying to make it work, and shows how these dilemmas can be resolved. It considers lessons to be learnt, implications for practice and recommendations for making multi-professional practice effective. Featuring useful guidance, theoretical frameworks and evidence-based insights into practice, this book is a key resource for students on courses studying early childhood and families, as well as social workers, teachers, support workers in children's centres, family support workers, health workers, and managers of a range of children and youth services.
