Your Baby’s Wake Windows: What Are They And How To Perfect Them!

If you’ve ever googled something even slightly related to baby sleep, you've probably seen the term 'wake windows' absolutely everywhere! And that's because getting wake windows right is one of the biggest game-changers for baby sleep (and parent sanity).

The problem is, you'll see different information everywhere and it can be truly overwhelming but with the right information, you'll be the most well rested parents around town!

What Are Wake Windows?

A wake window is simply the amount of time your baby stays awake between sleeps. During the first year of their life, wake windows can change rapidly which often causes a lot of confusion and inconsistencies and in many cases, seems to be the start of a child's sleep getting completely off track leading to chronic overtiredness and causing night waking, short naps, difficulty getting to sleep and much more!

Why Wake Windows Matter for Baby Sleep

When babies stay awake too long, their bodies release stress hormones like cortisol and adrenaline. That make it harder for them to fall asleep — even though they’re exhausted.

Getting wake windows right helps:

• Babies fall asleep faster

• Nap longer

• Decrease bedtime battles

• Reduce night waking

• Makes for easier settling or self-settling

• Makes an overall happier baby

  
  

In short: wake windows support healthy, restorative sleep and development

Handy Tips For Perfecting Wake Windows

If you really want to perfect your child's sleep, there are some things I could teach you about wake windows, how they truly work and where they often go wrong so strap in!

1) Laddering wake windows

You'll have seen that each group has a range of minutes/hours, this is because the best way to succeed at wake windows, is to ladder them! This means the shorter wake window happens in the morning, in between during the day and the longer wake window before bed. This helps to build sleep pressure before their 'big' night time sleep.

You'll see how I've laddered the wake windows in the routine examples coming up...

2) The power of a catnap Yes, I said it... There are times when we welcome a catnap. This happens when a child's ideal wake window falls too early for it to be bedtime but would throw bedtime out if we let them sleep their normal nap length. In this case, we put them down for a nap as usual but only give them 30 minutes of sleep (or more if time allows but never below 30 minutes). Meaning that they wake up with enough time to allow for their wake window and a reasonable bedtime. For babies, bedtime is ideal anywhere from 6 to 8pm.

You'll also see an example of how a catnap helps in the routine example below...

Note: Never allow a catnap for children having 1 nap per day. We call this a 'danger nap' 😅 because it refreshes the wake window, toddlers will be up for HOURS past bedtime.

And while on the topic of bedtimes, that brings us to number 3...

3) Adjusting bedtime as wake windows change

Because wake windows change quicker than a child reduces the number of naps they have, they end up having to squeeze in longer wake windows and the same amount of naps into a day so how does that work? To combat this, bedtime will get pushed out to a later time as their wake windows increase and will then jump forward when they drop a nap. This happens when a baby drops from 4 to 3 naps at around 5/6 months, 3 to 2 naps around 8 months and down to 1 nap at around 14 months.

For example, 7 month old having 3 naps will have a routine that looks similar to this:

6:30am: 2hr15m wake window

8:45am - 10am: Nap 1

10am: 2hr30m wake window

12:30 - 2pm: Nap 2

2pm: 2hr30m wake window

4:30pm - 5pm: Nap 3

5pm: 2hr45m wake window

7:45pm: Bedtime

Whereas, within the next month, the same baby, now 8 months old but dropped to 2 naps will do:

6:30am: 2hr30m wake window

9am - 11am: Nap 1

11am: 2hr30m wake window

1:30pm - 3:30pm: Nap 2

3:30pm: 3hr wake window

6:30pm: Bedtime

As you can see, bedtime is much earlier but will start to get later over the coming months as their wake window extends to 4 hours, before they drop down to 1 nap and their bedtime gets earlier again.

3) Look for sleepy cues

Use wake windows as a starting point but keep an eye out for sleep cues around these times and don't be afraid to put your baby down earlier if they are showing signs. Although, parents can report sleep cues to be very inconsistent or hard to see in some babies so that's why familiarising yourself with wake windows can be a better tactic. My advice as a sleep coach is use wake windows as your foundation and use sleep cues as confirmation.

Sleep cues include:

• Rubbing eyes

• Red eyebrows

• Glazed over eyes

• Staring into space

• Yawning

Unknown to some but we actually want to get them to bed BEFORE any crying/grizzling, head turning, back arching and more 'intense' signs of discomfort.

Now I've Spilt All My Secrets...

I know after this you'll probably think wake windows seems really complicated but this is just the reality on how fiddly baby sleep can be. Not knowing those extra tips are where I believe most people go wrong, quickly searching the wake windows for their babies age and not being given the information to use them correctly.

If you can familiarise yourself with all these techniques then getting good sleep from your baby will be a breeze for you and you'll have other parents asking how you do it! (At which point you can point them to this page 😝)

Once you understand how long your baby can comfortably stay awake, sleep starts to feel less mysterious and a lot more manageable 💛
