A Longitudinal Analysis Examining the Associations of Tummy Time With Active Playtime, Screen Time, and Sleep Time.

Background: Evidence links tummy time (ie, the time spent in awake prone positioning that is encouraged and supervised by an adult) to infants' health outcomes such as gross motor and total development. However, the associations between tummy time and other movement and sleep behaviors as the child develops remain unknown.
