Donor milk vs formula: which boosts breastfeeding in At-Risk newborns?
NCT ID NCT06315127
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether giving pasteurized donor milk instead of formula to newborns who need extra feeding helps mothers breastfeed longer. It includes babies born small, late preterm, or to mothers with diabetes. About 112 infants will be randomly assigned to receive donor milk or formula during their hospital stay, and researchers will check breastfeeding rates at 4 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- pasteurized human donor milk
- What this could lead to
- If donor milk works better than formula, it could help more mothers breastfeed exclusively for longer, improving infant health.
- What could go wrong
- This is a small, early-stage trial with only 112 infants, so results may not apply broadly. Donor milk is safe but may not significantly improve breastfeeding rates.
