Your 15-month-old baby is changing every day – and that includes their sleep patterns. This can lead to a lot of questions. For example, “How much should my 15-month-old be sleeping?”

Luckily, we’re here to help you sort it all out.


A Sample 15-Month-Old’s Sleep Schedule:

We’re using this timetable only as an example. Your baby’s a little individual with their own schedule.

We’re using these examples to focus on wake windows: the amount of time your baby is awake between naps and sleeps. Use this time to help gauge their next nap, as well as their sleepy cues – pulling ears, yawning.

Together these two tools can help you keep your baby’s sleep on track.

Learn more about wake windows and sleepy cues by checking out the Smart Sleep Coach by Pampers™. This easy-to-use app guides you step-by-step so you can teach your baby how to fall asleep faster and stay asleep longer for optimal development.

Many 15-month-olds are already on one nap, though some may still need 2. We’ve included sample schedules for both scenarios here. For more information on nap transitions, click here.

Sample Sleep Schedule for 15-Month-Olds with 2 Naps:

“Good morning!” 7:00 AM
Nap 1 10:15-11:30 AM Awake: 3 hrs. and 15 mins.

Nap: 1 hr. 15 mins.

Nap 2 3:15-4:15 PM Awake: 3 hrs. 45 min.

Nap: 1 hr.

Bedtime Routine 7:45 PM
“Good night!” 8:15 PM Awake: 4 hrs.

Sample Sleep Schedule for 15-Month-Olds with 1 Nap:

“Good morning!” 7:00 AM
Nap 1 12:00-2:30 PM Awake: 5 hrs.

Nap: 2.5 hrs.

Bedtime Routine 7:30 PM
“Good night!” 8:00 PM Awake: 5.5 hrs.

Q: How Many Total Hours Should a 15-Month-Old Sleep?

A 15-month-old should typically get about 13 hours of sleep over a 24-hour period.

Q: Can a 15-month-old baby sleep through the night?

Yes. By now most 15-month-olds sleep through the night, especially with sleep coaching.

Q: How much nighttime sleep for a 15-month-old?

As with 14-month-olds, 11 hours is a great number of hours for 15-month-olds to sleep each night.

Q: How much daytime sleep for a 15-month-old?

Still about 2-3 hours, usually in one nap, though sometimes split between 2.

Q: What is a 15-month-old’s wake window?

Wake windows for 15-month-olds taking only one nap is about 5-5.5 hours.

If your baby’s taking two naps, the first wake window is around 3 hours and 15 minutes, while the second may be a little longer, up to 3 hours and 45 minutes.

Q: Is there a 15-month-old regression?

Not technically, no, though some babies may already be experiencing their forthcoming 18-month regression.

Also, now that your baby’s over 12 months, you can let them sleep with a stuffed animal, blankie, or another comfort object to help them sleep.
