Infants, however, will wake up during that shift and probably need your help to get back to sleep.
Think about how you’ll barely wake in the middle of the night and shift positions or open your eyes for a split second before falling asleep again. The other difference between our cycles and baby's is that when we're shifting from one cycle to the next we might wake up, but we almost immediately fall back to sleep (unless affected by sleep disorders). When adults complete a sleep cycle and shift to the next cycle, we might briefly wake up or come close to waking up. Therefore, much of his or her sleep is comprised of light sleep, often accounting for more than half of their recommended 13-18 hours of shuteye. For you, deep sleep can persist up to 90 minutes at a time.įor your baby, it may not last an hour. Though you both cycle between periods of deep sleep and shorter stints of light REM cycle sleep, your baby does so many more times throughout the night. Your baby will first enter a lengthy period of light sleep from which it is easy for him or her to awaken. It's also the stage of sleep where we do most of our dreaming.Īs you can see below, your own sleep looks much different from the newborn sleep cycle. You might be fast asleep from the moment your head hits the pillow, while it takes infants longer to drift into a deep sleep than it does for you. This is where the brain starts to kick in and consolidates information and memories from the day before.
