Understanding Wake Windows for 9-Month-Olds

At 9 months, babies can handle 3 to 4 hours of awake time between sleep periods:

  • First wake window (morning): 3-3.5 hours
  • Second wake window: 3.5-3.75 hours
  • Last wake window (before bed): 4 hours - longest to build sleep pressure

9-Month Development & Sleep

At 9 months, babies are mastering crawling, may be cruising along furniture, and developing strong object permanence (understanding that things exist even when out of sight). These milestones can temporarily affect sleep as your baby practices new skills at night.

Keep bedtime routines consistent and calm. Allow plenty of daytime practice with new physical skills. If your baby stands up in the crib and cries, gently lay them back down at first, then let them practice falling to sitting on their own.
