(KSL News) -- Grandmother was right, swaddling does help new babies sleep. A new study finds wrapping newborns helps them sleep more soundly.
Little baby Otto is giving his lungs a workout. A diaper change will do the trick, for now, to help him sleep, but mom and dad are getting a lesson in swaddling.
A small study of 16 newborns finds babies who are swaddled sleep longer and wake spontaneously less often than babies who aren't bundled. Researchers say the wrapping reduces movement that can wake a baby. They note that it took less noise to arouse the swaddled babies when they were in the dream phase or REM sleep.
