Professor Oberman’s analysis of the purposes of punishment and Judith MacFarlane’s explanation of American defense options are illuminating, but I have reservations about the psychiatric contribution. The starting point must be classification, because there are many forms of infanticide, each with different causes and manifestations; this has been delegated to a lawyer, and not surprisingly her classification is incomplete. Five psychiatrists summarize postpartum disorders. They seem to recognize three entities—depression, psychosis, and obsessional disorders. The psychiatry of childbirth is much more complex than that (1). Conspicuously absent is any mention of severe mother-infant relationship disorders (hatred and rejection of the infant), which are crucial to fatal abuse and neglect; even the chapter on the mother-infant relationship deals only with minor forms of these disorders. These psychiatrists believe that "cognitive disorganization" sets puerperal psychosis apart as a distinct "organic" disease. This is a feature of acute polymorphic or cycloid psychoses, long known to be linked to childbirth, and (although not recognized by DSM) occurring in greater than 10% of nonpuerperal psychotic patients (2).
