All About Baby Wake Windows

Your baby’s wake windows are a critical part of your baby getting good sleep! Having appropriate wake windows can help your baby take better naps and sleep better at night!

I’ve been obsessed with sleep for a long time now—ever since I had my daughter 3.5 years ago. And now as a Baby and Toddler Sleep Consultant, I’m even more passionate about helping families get the rest they need.

And you know what? It all started with learning about my baby’s wake windows or baby’s wake times.

I read several sleep books when I was pregnant, including Babywise and I thought I knew what I was doing.

But we struggled with naps and early morning wake-ups for a while, despite my best efforts to keep my baby from getting overtired, implementing an eat, play, sleep routine, and setting up a nursery environment that was conducive for sleep.

The thing that I was missing was age-appropriate wake windows!

My daughter would often yawn after being up for 60 minutes. I was very tuned in to her sleep cues, so I would put her down for sleep as soon as I saw that little yawn or eye rub.

But then she would often wake up after 45 minutes, leaving me frustrated and confused on how to get her to sleep longer.

Then I learned about baby’s wake windows and it made all the difference in her naps and night sleep.

What are Wake Windows for Babies?

A baby’s wake window is the time that your baby is able to stay awake in between naps without getting overtired or being under-tired.

It’s the time they are awake—eating, playing, and getting their diaper changed. Your baby has an age-appropriate wake window, which is the sweet spot for making sure they aren’t overtired or under-tired.

Not following the correct wake windows for your baby can lead to your baby only napping for 30 minutes, your baby waking up too early, and a generally fussy baby who isn’t getting proper sleep.

Figuring out your baby’s wake windows can be a little tricky, but it doesn’t have to be!

When Should You Start Using Wake Windows?

You can start using wake windows right away, even with your newborn!

Wake windows are just watching the clock and getting your baby down for a nap before they get overtired. Sticking to age-appropriate wake windows is one of the best ways to optimize your baby’s sleep!

Do Wake Windows Include Feeding?

Yes! Wake window is the time period when your baby wakes up from one nap, before they go down for their next nap. Your baby is awake while feeding, so that is part of his wake window.

In the beginning, feeding will take up the majority of your baby’s wake window. As your baby grows, is able to stay awake longer, and is more efficient at feeds, their wake window won’t consist of just eating!

Wake Windows By Age

In general, most babies will have a range of time that they can stay awake before getting too tired. Some baby’s require a bit more wake time, while others need a little less wake time.

Here are wake window ranges, broken down from ages Newborn through 13 months old.

Use this baby awake time chart to find your baby’s age and their proper wake window:

  • Newborn to 6 weeks: 30 to 45 minutes
  • 7 to 10 weeks: 45 to 60 minutes
  • 11 weeks to 3.5 months: 1 to 1.5 hours
  • 3.5 to 5 months: 1.5 to 2 hours
  • 5 to 7 months: 2.5 to 3 hours
  • 8 to 13 months: 3 to 4 hours
  • 13 months+: 5 to 6 hours

How Long are Newborns Wake Windows?

Newborn wake windows are very tiny—just like those little babies!

Generally newborns can only stay awake for about 30 to 45 minutes before they need to go back to sleep. A newborn’s wake time is just about enough time for a feed, diaper change, and quick cuddle!

If your newborn has been awake for hours, it’s likely they are extremely overtired, and you just need to get them to sleep however you can. We really want to avoid an overtired baby, because sleep begets sleep!

You really can’t enforce a newborn schedule, but you can watch the clock to ensure they are put down within their wake window!

Three to Four Month Old Wake Windows

Around 3 months old, your baby can start staying awake a little longer! A good 3 month old wake windows can be up to 90 minutes. And a 4-month old wake window can typically be up to 2 hours total.

It gives you so much more time to play with your baby!

Five to Seven-Month Old Wake Windows

At 5 months old, a baby’s wake window increases and a good 5 month old wake window is between 2 to 2.5 hours.

Between 6 and 8 months your baby will be able to extend their wake windows even more until they are ready to transition to two naps.

Eight to 13 Month-Old Wake Windows

Once your baby drops the third nap, you’ll stick with these wake windows for a while! Babies this age can typically stay awake between 3 and 4 hours before they need to go to sleep again.

I love following a 3/3/3 hour wake window at this age, so wake times are split evenly throughout the day.

One-Year Old Wake Windows

Between 13 and 18 months your baby will be ready to transition to one nap and follow a one year old schedule. Your baby has come a long way since those newborn days where they just had minutes of awake time!

Understanding Baby’s Wake Windows

Wake windows can be tricky to understand, especially for first-time parents, so let’s see an example.

If your baby is 4-months old, she can probably do a 2-hour wake window.

If she wakes up at 7 am for the day, her first nap will be at 9 am. Hopefully she’ll sleep for about 1.5 to 2 hours, and then wake up around 10:30 am. You’ll feed her, change her diaper, and play before she’ll likely be ready for her next nap around 12:30 pm.

You can see a more detailed 4-month old schedule here.

Of course babies will always have off days if they are sick or had a restless night. But in general, your baby’s wake times will be consistent day-to-day until they are ready to make a change.

How to Stretch Wake Windows

Some babies will start to show sleepy cues early on in their wake window and you may think they need a nap long before they actually do. This is what happened frequently with my daughter!

Around 11-weeks old, she would yawn at the 60-minute-mark, but from trial and error, I knew she needed a little extra time in order to take a long and restorative nap.

The best analogy I can give for this is this. If your toddler is hungry at 4:30 pm but dinner will be ready at 5:00 pm. You don’t want to give your toddler a snack now because then they won’t eat dinner.

Instead, you want to make sure they are hungry enough to sit and eat dinner with the family.

Baby’s wake windows for sleep are similar!

If your baby has independent sleep habits and is still struggling with short naps. consider their wake window. You may have to stretch them a bit in order to get them to stay awake a little longer.

A good way to stretch your baby’s wake time is to go outside or change the scenery on them. A little sun and some fresh air usually helps them get past the hump they need in order to make it to the new wake time.

You can also try enlisting big brother or sister or the family dog to help distract your baby and keep them up for an extra 15 minutes or so.

As your baby gets used to the new wake window, you won’t have to work so hard to stretch them. Generally, you’ll want to stretch your baby’s wake windows when you are dropping a nap, like the 3-to-2 nap transition around 7 or 8 months.

Wake Windows vs Schedule

Once your baby moves to two naps (between 6 and 9 months), you can move from following wake windows each day to using a more consistent sleep schedule.

With a two-nap schedule, your baby will nap about 2.5 to 3.5 hours after they wake up. You’ll establish a 6-month old schedule that works for your baby and keep naps and bedtime consistent each day.

You’ll use the age appropriate wake window to set their schedule and won’t need to adjust your baby’s naps or bedtime based on when they woke up from their various naps.

Nap time and bed time will be the same each day, regardless of your baby’s naps that day, which helps regulate your baby’s clock and prep their body for sleep each day.

It also gives you much more predictability to plan your day, knowing when baby’s naps will be each day!

If you’re struggling with wake windows, my baby sleep cheat sheets have baby wake windows and sample schedules for ages Newborn through 3 Years old broken down by age as well as nap schedules for each age.

I really think a lot of baby sleep problems can be solved by having the right wake window for your baby. If your baby won’t sleep, check their timing and see if it needs adjustment!

Struggling with 6.5 month old. He usually wakes 7/7:30am but he’s first wake window he only lasts 30mins . What does this mean? What can I fix ?

Hi Ana,

Do you mean he is tired after 30 minutes? I would take him outside and offer him a change of scenery to try and give him a little extra wind before naptime.

Hope that helps, Amy

I have been tracking my daughters sleep for a little over 3 weeks now. I always begin her nap routine with enough time in theory for her to fall asleep within her wake windows. I have tried increasing it and decreasing it to see if that helps. Either I’m trying to get her to fall asleep within that time and she doesn’t and thereby really Goes over her wake window or she does fall asleep within her wake window and is up 30-45 minutes later. I haven’t been able to get her to connect her sleep cycles within a nap and extend that.

Hi Mishel,

It can be so tricky! How old is she?

Great article - one of the most helpful I’ve read!

My LO is 15 weeks, he will go to sleep in his crib in the day after a lot of shushing and singing and rocking but only ever for 30 mins! If he is held or in pram outside or in the car it’s much longer. Any advice?

Hi Jo,

So glad you found it helpful!

Babies wake up in between sleep cycles so if he is put to sleep through rocking or bouncing and then wakes up in a crib, he will likely have a hard time going back to sleep on his own. This is why I think independent sleep is so important!

Hope that helps! Amy

Hi Amy, great article! I am currently struggling with my 10 month old (nearly 11 months) having a split night everyday for weeks. Any advice would be great!

She is up for 1.5hours every night at around 2-3am. I have been following wake windows (3-3.5/3.25-3.5/3.75-4) but in your article you state that on 2 naps the naps should be at the same time everyday. The problem is that she wakes at different times every day ranging from 5:00-7am (I always make sure the first nap doesn’t happen before 9:30). I normally wake her from the first nap after an hour so she has a longer afternoon nap usually 1.5-2hours long (I sometimes have to wake her from this nap too). Bedtime normally falls between 7-7:30. At the moment she is getting between 9-10hours at night with the split night. She is normally sleeping a stretch of 6-7hours before she is up for the long waking before falling back asleep. During this time she doesn’t cry but is awake sucking her thumb, babbling, rolling etc. I don’t need to go into her but everyday she seems to be really tired. What can I do to help her to sleep through the night again?

Kind regards Sam

Hi Sam, Yes, definitely sounds like a split night! Regardless of when she wakes up every day, I would try and keep her in her crib until the desired wake up time. Then you count the wake windows from there so the naps are the same time each day, which really puts you on a set nap schedule each day. For example, if your desired wake up time is 7 am, you'd get baby up at 7 (even if she's awake at 6:30). have her first nap from 10 to 11 am, then second nap from 2:00 to 3:30 and bedtime at 7:30.

Hope that helps! Amy

Hi Amy-when stretching wake windows do you advise shortening naps, or pushing back bedtime? For example, if I’m pushing all wake windows by 15 min, would my naps shorten or baby go to bed an hour later than normal?

Amy Motroni

Hi Brittney,

It depends on the baby's age. Sometimes, lengthening wake windows makes it so baby drops a nap altogether. If you're in a transition, bedtime may be temporarily pushed back, but it usually means baby's sleep needs are decreasing. I hope that helps! Amy
