Influx of maternal hormones through the placenta into the fetal circulation often causes the newborn's breasts to be enlarged. In addition, some secretion (ie, witch's milk) may be evident. These changes disappear with time.

Mastitis neonatorum or infections of the breast tissue may also occur during the newborn period. Treatment includes antibiotics. If an abscess occurs, needle aspiration should be performed. Surgical drainage should be considered only when needle aspiration is unsuccessful, because an operation may damage the breast bud and result in reduction of adult breast size.
