This chapter focuses on a particular clinical problem and its management that examines theoretical perspectives that may be helpful for improving understanding of families. It also focuses as much as possible on the practical relevance of these concepts. The chapter outlines of family therapy, which discusses the attachment theory, and examines what happens when care within the family is not the best option. Family therapy is based on the idea that the family is a system. Systems theory can equally be applied to groups of professionals, such as the primary care team. Boundaries are the invisible lines between different subsystems, most importantly between parents on the one hand and their children on the other. A well-functioning family has clear demarcations between the roles of different members, and effective channels of communication. Children in the care system are likely to move from one placement to another, which means changing general practitioners frequently.
