Sex Differences in the Relation Between Supervision and Injury Risk Across Motor Development Stages: Transitioning From Infancy Into Toddlerhood.

Rationale: Addressing a notable gap in research on injuries during infancy, this longitudinal study examined sex differences in the relationship between parents' typical levels of supervision and infants' injuries across motor development stages.

Method: Parents were recruited and completed biweekly phone calls about their infant's motor skills. Once the infant was able to sit up independently, then a home visit was scheduled.
