Why does my baby have white discharge coming from his nipples? What can I do?

Usually normal. Discharge from the nipples is a normal response to the mother's hormones passing to the baby through the breast milk, and can occur in boys as well as girls. If the area around the nipple is red or tender, or if the baby is fussy, irritable or has a fever, they should be examined.
Breast discharge. If you have a newborn tht can be your hormones at work, but if your baby is older contact your doctor.
