Huckleberry | 9 Month Old Baby Sleep and Nap Schedule

If your baby is experiencing the 9 month sleep regression (also known as the 8 month sleep regression), predictable sleep patterns might be a bit trickier than you’re used to this month. We recommend continuing to prioritize naps and early bedtimes in order to help them sleep as well as they can during this time.

Hang in there -- this is an important period of typical baby development and a temporary phase!


IN THIS ARTICLE:


At 9 months of age, we’ll continue to aim for at least 14 hours of total sleep over a 24-hour period. That’s 11 - 12 hours at night and 2 - 3 hours during the day over 2 naps. Most children need 2.75 - 3.5 hours of awake time in between sleep periods at this age.

[Note: for children who were born early, we go by their adjusted age for sleep development.]

You aren’t alone if your baby is sitting, standing and/or cruising in their crib when they should be sleeping. Yes, it can be frustrating to see your baby play when they should be sleeping, but don’t repeatedly intervene. That can backfire, and lead to even more sleep issues! Instead, give them the opportunity to explore and wind down on their own. Resettle your baby every 10 - 15 minutes or so until they’re ready for sleep.

Babies will often start to protest more during their bedtime routine at this age. We recommend offering more comfort as needed, but aim to follow through with the healthy sleep habits that you’ve already established. This will help you maintain long term progress.

Note: Sleep needs vary by child and this chart should be viewed as an example.

9 month nap time and sleep schedule

Ideally, your baby will be taking two naps for a total of 2 - 3 hours of day sleep. Each nap should be at least 60 minutes long. 

Most babies will be ready to drop their third nap by 9 months old, and be ready for a 2-nap schedule with an earlier bedtime. If your baby is still taking three naps a day, they’ll likely transition to two naps over the next month. Signs that a baby is ready to drop a nap include: shorter naps, resisting one of the naps (particularly the last one), and/or consistently sleeping less than 10 hours a night.

Here’s what a typical day may look like at this age: 

Morning rise6:00 AM
1st nap8:45 AM - 10:15 AM (1.5 hour nap) 2.75 hours of awake time before morning nap
2nd nap1:45 PM - 3:15 PM (1.5 hour nap) 3.5 hours of awake time before afternoon nap
Get ready for sleep5:45 PM
Asleep6:45 PM 3.5 hours of awake time before bedtime

A typical bedtime at this age is 12 - 13 hours after waking in the morning. For example, if your baby wakes around 7:00 AM, then you’ll want to target a 7:00 PM - 8:00 PM bedtime. While some babies do well with a consistent “by the clock” bedtime (e.g. aiming for a 7:30 PM bedtime each night), other babies will continue to sleep better if their bedtime is determined according to their last wake window.

If your baby tends to get overtired easily and wakes more often at night when their wake windows are pushed too far, set bedtime for no more than 3.5 hours after the second nap. Resist making bedtime earlier than 6:00 PM, as that can lead to early rising issues.

9 month old baby sleep FAQ

Q: Can a 9 month old baby sleep through the night?

A:

Many babies can sleep through the night at this age. However, some babies aren’t able to comfortably last 12 hours or more in between the last night feeding and a family’s desired wake up time. In those cases, many pediatric sleep consultants agree that an early morning feeding (typically between 3:00 AM - 5:00 AM) can help lengthen night sleep.

Q: How often do 9 month old babies sleep?

A:

An average 9 month old baby needs two naps per day, with 2.75 - 3.5 hours of wake time in between sleep periods. The period of wakefulness before the first nap tends to be the shortest of the day, and the longest period of wakefulness comes at the end of the day. As a result, a 9 month old typically needs 3.5 hours of wake time before bedtime.

Q: How much nighttime sleep for a 9 month old?

A:

Most babies this age need at least 10 hours of night sleep, although 11 - 12 hours is ideal.

Q: How much awake time for a 9 month old?

A:

Aim for 2.75 - 3.5 hours of wakefulness in between sleep periods. Wake windows tend to increase throughout the day, with the longest period of wakefulness occurring before bedtime.

Q: How much daytime sleep for a 9 month old?

A:

9 month old babies typically need 2 - 3 hours of daytime sleep each day. When babies have short naps, it can result in wake windows that are too long and lead to difficulty falling asleep and staying asleep.
