Effects of Enriched Parent-Infant Interaction on Health in Early Life

The goal of this intervention is to improve the frequency and quality of active parent-infant interaction via infant-directed singing.

This intervention follows the same structure as the singing intervention but focuses on the use of passive music listening rather than live singing.

This intervention follows the same structure as the singing intervention, but without the musical elements, while emphasizing enriched parent- infant interaction in non-musical (or less-musical) contexts.
