A corollary of Winnicott's well-known dictum that “there is no such thing as a baby” (p. 99)1—meaning, of course, that without a mother, an infant cannot exist—is that there is no such thing as a child in treatment who is without parents. Despite this clinical fact, child psychoanalytic training programs traditionally have tended to pay relatively little attention to the importance of learning how to work with the parents of children in treatment. Early in my own clinical experience, I became aware of the necessity of working effectively not only with parents, but also at times with siblings, grandparents, and other family members, if child treatment is to be successful. In part, this was because, during my first year of child psychiatry fellowship at the University of Rochester Medical Center, I had the good fortune to participate in a wonderful course in family dynamics and interaction led by Marjorie Harle, the head of the Psychiatric Social Work Division.
