Understanding Your Baby's Sleep Cycles

Understanding Your Baby's Sleep Cycles

A baby's sleep cycles change as they develop, and are different from adult sleep cycles: 
  • Newborns
    Sleep in cycles of 20–50 minutes, alternating between active and quiet sleep. During active sleep, babies may move around, cry, or breathe irregularly. During quiet sleep, they're more still and breathe more evenly. Newborns often wake up between sleep cycles and may need help falling back asleep. 
  • 3–6 months
    Babies start to have more deep sleep and less active sleep. They may sleep for 10–18 hours, with some waking up at night. 
  • 6–12 months
    Babies' sleep patterns become more like adults', sleeping 10–16 hours a day. They may sleep for 2–4 hours during the day and up to 12 hours at night. 
  • 5 years
    Children's sleep architecture, or how much time they spend in each sleep stage, starts to mirror that of adults. 
Here are some other things to know about babies and sleep:
  • Babies may wake up frequently due to hunger or needing to be changed. 
  • Babies may start to respond to light and dark instead of hunger around 4–8 weeks. 
  • Babies may rub their eyes, yawn, or fuss when they're getting ready for sleep. 
  • Breastfeeding can help babies settle and relax. 
  • Babies form memories and practice new skills during REM sleep.
