9 month old sleep schedule: wake windows, naps and a sample day

Nine months is usually settled two-nap territory. Days get longer and more active, and naps often become more predictable by the clock.

A starting point built from age-typical wake windows and nap lengths. Your baby’s own cues come first.

9 month old sample schedule

Here is one example day for a 9 month old who wakes at 7:00 am. It uses age-typical wake windows of about 3 h, a little shorter in the morning and a little longer before bed, and naps of about 1 h 10 min.

TimeWhatAwake before
7:00 am Wake up for the day -
9:40 am - 10:55 am Nap (1 h 10 min) 2 h 40 min
1:55 pm - 3:05 pm Nap (1 h 10 min) 3 h
6:40 pm Bedtime 3 h 35 min

That is about 2 h 25 min of day sleep. Wake earlier or later and everything shifts with it: use the schedule maker below to set your own wake-up time.

Most 9 month olds do well with wake windows of about 3 to 3.5 hours and two naps. Total day sleep is often about 2.5 to 3 hours.

Clock-based naps

Many families find naps around 9:30 to 10 am and 2 to 2:30 pm work well at this age. A predictable day helps your baby’s body clock, so try to keep wake-up time within about 30 minutes each morning.

Night feeds

By 9 months many babies get what they need during the day. Some still wake to feed. Whether to night-wean, and how, is a conversation to have with your pediatrician.

Standing in the crib

If your baby is pulling up, lower the crib mattress to its lowest setting. Practice sitting down from standing during the day.

Wake windows at 9 months

A wake window is the time your baby is awake between one sleep and the next. At 9 months it is usually 2 h 30 min to 3 h 30 min. Most babies manage the shortest window in the morning and the longest before bedtime, as sleep pressure builds through the day. If your baby fights sleep and only drops off after a long time, the window may be too short. If they melt down before naps, it may be too long. See all ages on our wake windows by age chart.

How much sleep does a 9 month old need?

The American Academy of Sleep Medicine recommends 12 to 16 hours in 24 hours at this age, including naps. Some healthy babies sleep a bit more or less. Watch your baby rather than the number: a baby who is mostly content when awake, and feeding and growing well, is usually getting enough sleep.

Safe sleep: every sleep on the back, on a firm, flat surface, with no pillows, blankets, bumpers or toys. Share a room, not a bed, for at least the first 6 months.

Questions parents ask

How long should a 9 month old nap?

Usually 1 to 1.5 hours per nap, across 2 naps.

What time should a 9 month old go to bed?

Often between 6:30 and 7:30 pm, about 3 to 3.5 hours after the afternoon nap ends.

Should a 9 month old still wake at night?

Some do and some do not. Brief wakings between sleep cycles are normal at every age. Ask your pediatrician if you are wondering whether night feeds are still needed.
