The experimental intervention, Play2Sleep, will occur during a home visit when the infant is 5 months old and will consist of video-recording each parent engaging in a structured play session with their infant. Immediately following the interaction sequence, the video-recording will be reviewed with the parent. Positive feedback on parental behaviors that promote interaction and child development will be provided during the video review. This will include the identification of the infant's social and sleep related cues. In addition to the standard public health handout on infant sleep, a handout on parent-infant behaviours will be given to encourage one or two areas that parents can continue to develop. During the video-recording and review, the other parent will not be present. The structured play sequence will follow established protocols in the Parent-Child Interaction Teaching Scale manual. The comparison group will receive only the standard public health handout.
