The Owlet Dream Sock shows acceptable feasibility for capturing high-density newborn sleep data to capture developmental changes in sleep patterns over the first weeks of life.
Newborns exhibited two common types of sleep bouts: light-only bouts and full sleep cycles.
On average, sleep bouts began around 11:48 AM, and newborns spent approximately 172 monitoring minutes awake, 536 minutes in light sleep, and 54 minutes in deep sleep per day.
The duration of deep sleep and the number of full sleep cycles increased each week over the assessment period.
Daytime sleep minutes decreased over the assessment period, while nighttime sleep minutes did not change.
The Owlet Dream Sock demonstrated acceptable feasibility for capturing high-density newborn sleep data in naturalistic home environments.
This research suggests that a consumer wearable device called the Owlet Dream Sock can be used to track newborn sleep patterns at home over the first weeks of life. In a study of 39 newborns monitored for 14 days, researchers found that babies typically had two kinds of sleep episodes: shorter ones involving only light sleep, and longer full cycles that included deep sleep. On a typical day, newborns spent about 172 minutes awake, 536 minutes in light sleep, and 54 minutes in deep sleep, with sleep bouts beginning on average around midday. The study also found that over the two-week monitoring period, the amount of deep sleep and the number of complete sleep cycles increased week by week, while time spent awake or in light sleep stayed the same. Daytime sleep decreased over the period, but nighttime sleep remained stable. These findings suggest that even in the first weeks of life, measurable changes in sleep organization are already occurring. This research matters because tracking newborn sleep at home in detail has historically been difficult, typically requiring lab-based equipment. This study suggests that an off-the-shelf consumer device can feasibly collect meaningful, high-density sleep data in real-world home settings, potentially enabling larger-scale studies of how early sleep patterns relate to infant development and health outcomes.
