The endocrine glands are considered better organized than other systems.

Disturbances are most often related to maternally provided hormones (estrogen, luteal, and prolactin) that may cause the following conditions:

a. Vaginal discharge and/or bleeding may occur in female infants.

This discharge is white mucoid in color. Bleeding may occur as a result of withdrawal from maternal hormones at the time of birth. There are usually only a few blood spots seen on the diapers. The entire process terminates in one to two days.

b. Enlargement of the mammary glands may occur in both sexes.

This is particularly noticeable about the third day of life. Breast secretion may also occur. Swelling usually subsides in two to three weeks. The breast should not be squeezed; it only increases the chances of infection and injuries to the tender tissue.
