5 Month Old Wake Windows: How Long Should a 5 Month Old Stay Awake?
At 5 months, wake windows stretch to about 2 to 2.5 hours and most babies settle into a solid 3-nap rhythm. Awake time is now long enough that the timing of the last window before bed really matters.
A wake window is how long your baby can comfortably stay awake before becoming overtired. For the full chart see wake windows by age, and for a full sample day see the 5 month old sleep schedule.

Getting the 5 month windows right
- Short naps return: if naps shorten after the 4 month change, check that the window was not too long. See why babies take short naps.
- Fights the third nap: the catnap is often short and may start to disappear. If the third nap fails, bring bedtime earlier so your baby is not overtired.
- Early morning waking: usually the final wake window is too long or bedtime is too late. Tighten the last window first.
This is exactly what Baby Signal helps with. Instead of guessing whether to stretch or shorten the next window, you describe what happened and get one clear adjustment for your baby's age and history. Get Baby Signal and stop watching the clock.
The takeaway
5 month old wake windows run about 2 to 2.5 hours across 3 naps. Keep the first window around 2 hours, lengthen toward bedtime, and protect an early bedtime if a nap is short. Next up: 6 month wake windows and the baby sleep schedule by age guide.
Frequently asked questions
How long should a 5 month old stay awake?
About 2 to 2.5 hours between sleeps. The first wake window is usually around 2 hours and the last before bed is the longest.
How many naps does a 5 month old take?
Most 5 month olds take 3 naps a day, though the third nap is often a short catnap that begins to disappear toward 6-7 months.

Early morning waking at this age is usually caused by a final wake window that is too long or a bedtime that is too late. Tighten the last window and aim for an earlier bedtime.
What is a good bedtime for a 5 month old?
Most 5 month olds do well with a bedtime between 6:30 and 7:30 pm, set by the last wake window after the final nap rather than a fixed clock time.
