Milk from a Newborn Baby Boy's Nipples - What You Need to Know
This is a well-known normal newborn finding called neonatal galactorrhea (also known as "witch's milk"). It happens in both male and female newborns.
What is it?
A milky white discharge from a newborn's nipples, sometimes with a small swelling or lump under the nipple (breast nodule). It occurs in about 5% of newborns, in both sexes.
Why does it happen?
During pregnancy, high levels of maternal estrogen pass through the placenta into the baby's bloodstream. This stimulates the baby's breast tissue and can cause it to produce a small amount of milk. The mother's hormones can persist in the baby's body for several weeks after birth. It is also more common in breastfed babies (since estrogen is present in breast milk too), and less common in premature infants.
Should you try to remove/squeeze out the milk?
No. Do NOT massage, squeeze, or stimulate the baby's breast tissue.
This is a common cultural practice in some regions, but it is harmful and strongly discouraged by pediatricians. Here is why:
- Squeezing or massaging the nipple forces bacteria into the milk glands
- This can lead to mastitis (breast infection) or a breast abscess in the baby
- Stimulating the tissue can also prolong the discharge and increase production
What should you do?
- Leave it alone - the discharge will resolve on its own, usually within a few weeks to 2 months
- Keep the area clean and dry
- Do not press, massage, or manipulate the nipple/breast area
- Mention it to your pediatrician at the routine well-baby check
When to see a doctor?
Consult a doctor if you notice:
- Redness, warmth, or tenderness around the nipple/breast (signs of mastitis/infection)
- The discharge is bloody
- The discharge continues beyond 2 months of age
- The discharge is one-sided and persistent/spontaneous
- The baby has a fever
Bottom Line
Milk from a newborn boy's nipples is normal and harmless. It goes away on its own. The most important thing is to not squeeze or massage the area, as that is the main way it turns into a problem. Reassure family members who may want to try to "remove" the milk - this can seriously harm the baby.
