Commentary on Sander's paper, “Where are we going in the field of infant mental health?”.

In this article, the author describes psychoanalytic therapist Louis W. Sander's new ways of exploring the child-caretaker relationship. Nearly two decades ago in pioneering work on newborn state organization, Sander studied the infant-caretaker relationship by describing each infant's uniquely characteristic regulatory patterns in the context of his or her particular and unique care taking environment. Sander's ideas about the infant-caregiver system are profound in their implications for the new way: to investigate and understand development.
