Curiosa paediatrica V: Inverted nipples.
Inverted, retracted or indrawn nipples are established in very early infancy, perhaps even prenatally, and are to be regarded as a developmental mammary malformation which is not corrigible by any manipulation. This fact should be recognized by parents and by antenatal supervisors who are consulted or called upon to advise about breast-feeding.
