Could donor milk give late preterm babies a healthier start than formula?

NCT ID NCT03220282

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares banked donor breast milk to preterm formula for late preterm infants (born at 34–36 weeks) who need extra nutrition while their mothers' milk supply increases. Researchers will track the babies' weight gain and analyze their gut bacteria to see which supplement supports healthier growth and microbial balance. The goal is to determine whether donor milk should be offered more widely to this group.

What this could mean

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

Active substance

donor breast milk

What this could lead to

If donor milk helps late preterm babies grow and develop healthy gut bacteria, it could become a standard supplement for these infants.

What could go wrong

This is a small, early-stage study with only 48 babies, so results may not apply to all preterm infants. Donor milk is pasteurized and may lack some nutrients found in fresh mother's milk.
