Soothing sounds boost breastfeeding success in newborns
NCT ID NCT07537218
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether playing lullabies (sung by a woman or a man) or white noise during breastfeeding helps newborns feed more successfully. 160 healthy full-term babies were randomly assigned to one of four groups: female lullaby, male lullaby, white noise, or no sound. Researchers measured breastfeeding success using a standard scale. The goal was to see if these sounds make breastfeeding easier for newborns.
