Summary

This pilot study looked at whether giving donor human milk instead of formula to full-term babies whose mothers received antibiotics during labor could improve their gut bacteria and health. The study included 105 infants born vaginally at full term. Researchers compared the babies' gut microbiomes, sleep, growth, and their mothers' well-being between the two feeding groups.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: donor human milk
What this could lead to: If donor milk is shown to improve gut bacteria balance and health in antibiotic-exposed infants, it could support broader use of donor milk over formula for these babies.
What could go wrong: This is a small pilot study with only 105 participants, so results may not be conclusive. The study is completed but not yet published, and findings may not apply to all infants or settings.
