Outline of Final Research Achievements |
This study aimed to develop a home-monitoring system for recording and auto-analyzing nocturnal infant sleep-wake during co-sleeping, and to describe nocturnal infant sleep at 2 and 25 weeks after birth. Developed was an image processing and a hybrid-sensing activity counter to monitor twelve low-risk infants. Sleep-wake patterns were analyze at 2, 4, 7, 12, 25 weeks after birth. Longitudinal data indicated sleep variables increased and wake variables decreased. Sleep development by 12-week. The majority of the longest sleep periods were observed during the first sleep period resembling adult sleep. Adult sleep patterns may appear as early as 12 weeks.
