Breast Milk on Baby Eczema: What Two Small Studies Can and Cannot Prove

Dr. Arsy Editorial Team · November 9, 2026

Some parents hear that applying breast milk to a baby’s eczema may soothe the skin. Two clinical studies have examined topical human milk, but their results are limited and do not establish that it is an effective substitute for a clinician’s eczema treatment.^[6][7]

The first comparison

One single-site randomized study compared topical human milk with 1% hydrocortisone ointment in infants with mild-to-moderate atopic dermatitis. Its abstract reported no statistically significant differences between groups over 21 days. A finding of “no significant difference” does not, on its own, prove that treatments are equivalent. The short follow-up and single setting limit what can be generalized.^[6]

The split-body pilot

In a separate small study, investigators compared milk plus emollient on one eczema spot with emollient alone on a comparable spot. Nine children entered and six completed the study. The investigators found no clear effect from adding milk. Bacteria were found in some milk and skin samples; the study did not identify a secondary infection attributable to milk application. Because very few children completed the study, it cannot exclude every possible benefit or risk.^[7]

What parents should take away

These studies do not justify replacing prescribed eczema medicines with breast milk, applying home remedies to infected skin, or assuming that a rash is eczema. If you are considering a home remedy, ask a pediatric clinician first, particularly for a newborn or for broken, painful or weeping skin. The question of topical application is different from the nutritional role of feeding breast milk.

Care that is tailored to the child

A clinician can assess whether the rash is atopic dermatitis and recommend an age-appropriate routine. Pediatric guidelines support moisturizers for children with atopic dermatitis and discuss additional treatments when needed. Ask how much to apply, where and for how long, and what to do if symptoms persist.^[17][19]

When to seek help

Seek prompt medical assessment for fever, skin that becomes painful or rapidly more red, pus, or clusters of blisters. Contact the child’s clinician if sleep is disrupted, the rash is spreading, or the agreed treatment plan is not helping. Early assessment can help identify infection or a different diagnosis.
