Beyond criminal intent: infant-directed violence as a symptom of postpartum psychosis

Postpartum psychosis is a rare but severe psychiatric emergency in which infant-directed violence, although uncommon, is best understood as a manifestation of acute psychotic illness rather than enduring maternal hostility or conventional criminal intent. The psychotic content of postpartum psychosis is often infant focus, with profound disturbances in reality testing that transform the mother's perception of her infant, framing the child through delusions and hallucinations as an object of danger, salvation, contamination, or divine significance. In the cases of infanticide or filicide, the violence directed at the child, although objectively tragic are subjectively protective or morally necessary. Drawing on the existing literature on postpartum psychotic phenomenology, this conceptual analysis uses two contrasting clinical cases as illustrative examples-one involving infanticide and one without infant-directed violence-to examine how infant-focused delusions can shape perception and behavior. By contrasting these cases, the article demonstrates how infant-focused delusions directly dictate behavior and explores why the infant becomes the primary object of the mother's psychotic experience. Finally, the paper discusses the implications of this comparative framework for forensic assessment, criminal responsibility, violence risk evaluation, and clinical intervention.
