    Hormonal effects in newborns

    Under the influence of maternal hormones during pregnancy a newborn may exhibit signs of hormone exposure after birth, such as enlarged breasts.  In addition to the breast enlargement, there may be some discharge from the nipples. This too is common and should be of no concern, disappearing within 2 weeks. The discharge is called witch's milk.

    Hormonal effects in newborns occur because, while they are in the womb, babies are exposed to many chemicals (hormones) present in the mother’s bloodstream. After birth, the infants are no longer exposed to these hormones. This exposure may cause temporary conditions in a newborn.
