If your baby has been diagnosed with or you suspect milk discharge from newborn nipples (witch's milk), here is what the evidence says.

The short answer

A small amount of milky discharge from a newborn's nipples (called witch's milk or neonatal galactorrhea) is normal and occurs in both boys and girls. It is caused by maternal hormones that crossed the placenta before birth. Do not squeeze or express the fluid. It resolves on its own within a few weeks.

Key takeaways

  • A small amount of milky discharge from a newborn's nipples (called witch's milk or neonatal galactorrhea) is normal and occurs in both boys and girls. It is caused by maternal hormones that crossed the placenta before birth. Do not squeeze or express the fluid. It resolves on its own within a few weeks.
  • Usually normal when: Small amount of milky white discharge from nipples in a newborn in the first few weeks
  • Call your doctor if: The breast area becomes red, swollen, warm, or tender, which could indicate mastitis requiring antibiotics
  • Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”

What Parents Should Know

According to AAP, NIH guidelines, a small amount of milky discharge from a newborn's nipples (called witch's milk or neonatal galactorrhea) is normal and occurs in both boys and girls. It is caused by maternal hormones that crossed the placenta before birth. Do not squeeze or express the fluid. It resolves on its own within a few weeks. At 0-1 month, witch's milk is a normal phenomenon caused by the same maternal estrogen and prolactin hormones that cause breast tissue swelling in newborns. Up to 5% of newborns produce enough milk to be visible. The discharge is typically small in amount, milky white, and comes from one or both nipples. It is harmless and self-resolving. The most important thing is to avoid squeezing, pressing, or trying to express the milk, as this can stimulate more production, irritate the tissue, and potentially cause infection (mastitis). It is generally considered normal when small amount of milky white discharge from nipples in a newborn in the first few weeks. However, you should contact your pediatrician promptly if the breast area becomes red, swollen, warm, or tender, which could indicate mastitis requiring antibiotics.

By Age

What to expect by age

0-1 month

Witch's milk is a normal phenomenon caused by the same maternal estrogen and prolactin hormones that cause breast tissue swelling in newborns. Up to 5% of newborns produce enough milk to be visible. The discharge is typically small in amount, milky white, and comes from one or both nipples. It is harmless and self-resolving. The most important thing is to avoid squeezing, pressing, or trying to express the milk, as this can stimulate more production, irritate the tissue, and potentially cause infection (mastitis).

1-3 months

The milk production should diminish and stop as maternal hormones clear from the baby's body. This typically happens within the first few weeks but can occasionally persist for up to 2 months. Continue to avoid manipulating the breast tissue.

3-6 months

Witch's milk should have completely resolved. Any new nipple discharge at this age is unusual and should be evaluated by your pediatrician.

6-12 months

No nipple discharge should be present. Any nipple discharge beyond the newborn period warrants medical evaluation.

What to Tell Your Pediatrician

  • Describe when you first noticed milk discharge from newborn nipples (witch's milk) and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if witch's milk persists beyond 2 months.
  • Mention if the discharge appears to be increasing rather than decreasing.
  • Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
  • Bring a list of any questions or observations you want to discuss at the appointment.

Breast Buds and Swelling in Newborns

Swollen breast tissue (breast buds) in newborns is very common and occurs in both boys and girls. It is caused by the mother's hormones (estrogen) that crossed the placenta before birth. The swelling is harmless, may last a few weeks to months, and resolves on its own. Do not squeeze or massage the breast tissue.

Swollen Genitals in Newborns

Swollen genitals in newborns are very common and normal for both boys and girls. The swelling is caused by maternal hormones that crossed the placenta and by fluid retention during delivery. The swelling is temporary and typically resolves within the first few days to weeks of life without any treatment.

Breast Buds and Swelling in Newborns

Swollen breast tissue (breast buds) in newborns is very common and occurs in both boys and girls. It is caused by the mother's hormones (estrogen) that crossed the placenta before birth.

The swelling is temporary and typically resolves within the first few days to weeks of life without any treatment.

My Baby's Head Shape Looks Abnormal

Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.

Achondroplasia (Dwarfism) in Babies

Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.

Adenoid Hypertrophy and Breathing

Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.

Adrenoleukodystrophy (ALD) in Babies

X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.
