Age Appropriate Awake Windows & Help Understanding Sleep Cues

When exhausted parents reach out to me, one of the first questions I ask is about awake windows. How much awake time are they giving their child before offering a nap or bedtime? All too often, these awake windows are much too long. 

An overtired baby has a harder time calming, falling asleep and staying asleep. Being overtired is the #1 culprit for early morning wake-ups too. So how do you know if your baby is tired? Here are a few sleep cues to look for: 

Getting Sleepy: Baby may start being uninterested in toys or maybe even you; looking off into space and giving cues like red eyebrows. Start working on your nap/bedtime routine now to get them to sleep before they are overtired. 

Time For Bed: This is when you will see more signs like yawning, red eyes, and fussing. Now is the time to get your child in bed so they can fall asleep. Allow enough time so that you don't skip your regular bedtime routine. You can adjust and make it a bit shorter if needed, but always offer a consistent routine to help signal that it is bedtime. 

Overtired: Your baby may become inconsolable, show signs like red eyes or pulling at their ears. You may even see a burst of energy. This “second wind” is definitely a sign that they are overtired. When your baby is overtired, you may find that it takes longer to get your little one to settle and fall asleep. 

Still struggling to understand sleep cues?

Along with the sleep cues listed above, you may also use their age-appropriate awake windows as a guide to know when to offer their next sleep. During the first 4-5 months, I suggest following a routine rather than a strict schedule. Babies and children thrive on a routine, and you may notice things feeling easier once you have a good routine in place.

Here are some age-specific guidelines that I recommend:

0-3 months: The maximum awake time during the newborn stage is 60-90 minutes. This is often just enough time to change a dirty diaper, feed your baby, snuggle and change another dirty diaper before they doze off. Naps in the early months are often short and frequent. 

3-6 months: Naps should be offered after 1.5-2.5 hours of awake time. Most often this allows for three naps. Around the 5-month mark is when we start seeing naps consolidating from short snoozes to longer naps. 

6-9 months: You will start seeing your baby consolidate to two naps with 2.5-3 hours of awake time in between. 

9-13 months: At this age, naps should be offered after about 2.5-4 hours of awake time between each sleep. The shortest awake window should be offered in the morning while the longest awake window is between the last nap and bedtime. 

13-18 months: This is the most common time to transition to 1 nap with 4.5-6 hours of awake time. Make sure to offer an early bedtime if the nap is short to avoid them becoming overtired. 

18 months-3 years: Continue to offer a nap with 5-6 hours of awake time. Your child is usually ready to drop the nap altogether between 3-4 years old. It’s still important to offer a “quiet time” until they are able to go from morning wakeup to bedtime without major meltdowns. It’s also wonderful for parents and caregivers to have some downtime in the middle of the day, too.

    I have a 13 month old that is sleeping independently for bed time but I am having trouble figuring her wakes times for her naps. I’ve noticed she needs to be awake 5 hours before bedtime so she sleeps throughout the night. Our schedule is usually wake time 6:30 am or 7 am and bedtime is 7pm. I was offering her a nap at 11 but by then she was overtired and didn’t nap independently so I moved it up to 9:30am. She takes that nap for an hour so she wakes up at 10:40am or so. Now her second nap would be up around 2 but she has been refusing to sleep independently for that nap. She will stay up until I go in and do a contact nap at 3pm but by then it’s already late. I’ve also thought about just doing one nap but I’m afraid she’ll be overtired if I offer her morning nap later. Can you help?

    Thank you!

    Hello Stacey (16 week old daughter)
    Your daughter sounds like she’s still right on track with her naps. I don’t usually see the naps consolidate until closer to 6 months (give or take). You may start to notice she’s able to stay awake slightly longer in the afternoon while the morning nap is the shortest awake window.
    You can start gently stretching her in 5-15 minutes increments to offer longer awake windows as she’s getting older and you see her being more ready for this.

    Hi Stacey (7.5 month old son)
    I would look at your sons daily schedule to evaluate that he’s getting the right amount of sleep and awake windows. If he’s actually hungry at 10pm and eating a full feed vs a comfort feed to get back to sleep, I’d also look at talking to his pediatrician about weaning that feed and pushing it later.

    Hello Rhiannon!
    Early morning waking can be super frustrating. It does sound like you’ve tried a lot of different things. I would definitely keep his nap time very consistent and make sure he has plenty of awake time before bed so that he really has a drive to sleep.
    You can also try something called “wake to sleep” to help break up his sleep cycle and hopefully sleep later into the morning. I have an example/explanation of this in my Instagram Stories

    Hi, my son will be 2yrs in 3 weeks time and has always been an ‘early riser’, I have researched children’s sleep since he was 4 months, so I understand overtiredness etc, but nothing works. I came to accept that 5am was his time as I couldn’t fix this. But the last 5-6 weeks he has been waking anything from 3.30-4.30… and will not go back to sleep even though he’s tired. I keep him in his cot until 6, but he just screams until we get him up, unless I stay with him and then he will lie there, but still won’t sleep. He settles fine in the evening (mostly) and goes down between 6&7pm depending on when he woke from his nap. His nap is around 1-1.5 hours. I have tried a morning nap and also moved it to the afternoon but nothing works, I’m guessing it’s just one vicious cycle of overtiredness that I can’t break because he’s up so early… his awake time, wether morning or afternoon, is always going to be too long while he’s waking up at this time. I thought to give two naps to try and sort it, but he never seems to go for a second nap now as he’s not used to it. Help!
    I feel like I have been exhausted for two years solid!
