The Maternal-Fetal Relationship and the Basis of Prenatal Obligation

Kingma and Woollard argue that many forms of harmful prenatal conduct are better understood as allowing rather than doing harm and that treating them as doing harm creates a justificatory bypass around pregnant people’s autonomy. I take up their invitation to examine special obligations directly. I argue that pregnancy is a structured dependency relationship marked by total dependence, vulnerability, and causal responsibility. Together, these features generate significant though bounded duties of care. The account avoids fetal personhood claims and coercive maximalism while explaining why omission-based prenatal harms can carry normative significance beyond the doing/allowing classification.
