Summary

This study tests whether offering mothers in São Paulo gift packages—like diapers, hygiene products, or toys—at six months after birth can increase the number of babies who are exclusively breastfed. About 300 mothers who recently gave birth will be randomly assigned to receive no gift, an unconditional gift, or a gift only if they are still exclusively breastfeeding. All mothers get education on breastfeeding benefits, and researchers will compare the groups to see if the gifts make a difference in breastfeeding rates and child health.

What this could mean

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

Active substance
Social transfers (gift packages of diapers, hygiene products, toys, or transport vouchers) offered to mothers at 6 months postpartum
What this could lead to
If effective, this could offer a simple, scalable way to boost exclusive breastfeeding rates and improve child health in low-income settings.
What could go wrong
The trial is relatively small and relies on self-reported breastfeeding, which may not reflect real-world impact. The gifts may not be enough to change behavior.
