Singing to your baby may boost mood and sleep, new study finds

This study tested whether simple activities like singing, listening to music, or reading books with your baby can improve health outcomes for both infants and parents. Over 200 families with babies up to 4 months old were randomly assigned to one of four groups: interactive singing, passive music listening, interactive book reading, or no special activity. Researchers used smartphone surveys to track infant mood, sleep, crying, and parent well-being over 8 months. The goal is to find low-cost ways to support early development and family health.
