Abstract
OBJECTIVES
Initial studies indicate more independent and consolidated sleep in the first few months in infants who sleep separately. Little is known, however, about the relationship of sleep location (separate room, room-sharing, bed-sharing) with sleep outcomes in older infants (ages 6-12 months). It was expected that those who sleep in a separate room would have better parent-perceived sleep outcomes and more positive sleep health behaviors.
METHODS
Parents of 6236 infants (6-12 months) in the United States (US) and 3798 in an international sample (Australia, Brazil, Canada, Great Britain, and New Zealand) completed a smartphone app-based expanded version of the validated Brief Infant Sleep Questionnaire.
RESULTS
A total of 37.2% of the infants in the US and 48.4% in the international sample slept in a separate room. In both samples, infants who slept in a separate room as opposed to room-sharing or bed-sharing had parent-perceived sleep outcomes and sleep-related behaviors that reflected earlier bedtimes, shorter time to fall asleep, more nighttime and total sleep, and increased sleep consolidation. They were also more likely to have a consistent bedtime routine and to fall asleep independently, as well as less likely to feed to sleep at bedtime and during the night. In addition, parents of separate room sleepers perceived bedtime to be less difficult and sleep to be better overall.
CONCLUSIONS
Overall, 6- to 12-month-old infants who slept in a separate room had better reported sleep outcomes and fewer parent-perceived disturbances at bedtime than infants who room-shared with their parents, as well compared to those who slept in their parents' bed.
