Why won’t my baby sleep past 4 am? This is our most popular blog post, and for good reason. It’s the most common sleep question parents ask, and we’ve got you covered. Here at the Sleeper Teachers we’ve helped hundreds of families resolve their children’s early morning wakes. If you’ve tried everything you can think of — moving bedtime earlier, later, changing nap schedules and wake windows, adding a noise machine, ruling out hunger — but nothing seems to be working, this detailed 10 Step Guide to Getting Rid of Early Morning Wakes is for you. The guide will walk you step-by-step through troubleshooting pesky early morning wakes so that your child can get the sleep they need, and so can you!

While the blog post serves as an overview, the guide is your deep dive and check list for getting to the bottom of why your child is experiencing these early morning wakes. Read on for some more information about early morning wakes and why they may occur.

So Why Can’t my Baby Sleep Past 4 am?

If you’ve been dealing with early wakes for awhile, you may have wondered any of the following. Is it a developmental milestone? A regression? Is my baby getting too much sleep during the day, or not enough? Maybe they’re just hungry. Maybe they’re too hot, or too cold. Maybe they are just an early riser?

Well, the truth is that it could be any of those things, and it could be a combination of several of them. What that means, and what you’re probably already aware of, is that sleep (for all ages) is tremendously complicated.

As babies, toddlers and children, our little one’s bodies and brains are rapidly going through significant changes, and by the time they’ve got one issue under control, a new one surely pops up to take its place. And as adults, our minds RACE at 4 am.

There are factors you can control, obviously. If baby’s too hot, you can turn up the AC or put a fan in the room. If they’re teething, a little Children’s Tylenol can often solve the problem, at least temporarily.

But those are the simple fixes. The reason most people have such a challenging time with their babies’ sleep is because of problems that aren’t so simple and don’t have obvious solutions.

How Does This Play Out?

Imagine this scenario: An 18 month old child gets plenty of fresh air and sunlight during the day, goes down easily for a long, restful nap, but when bedtime rolls around, suddenly they’re full of energy and want to play. When they’re told it’s time for bed, they get upset and bedtime becomes a battle. Once they do finally get to sleep, they wake up several times at night and never sleep past 4 am.people-3218556_640

So what’s going on? Is baby getting too much sleep during the day? That would be the reasonable assumption, for sure. After all, if us grown-ups were to take a 3-hour nap in the afternoon, there’s a good chance we’d have a hard time falling and staying asleep that night.

But the opposite is almost always the case. What baby is demonstrating in this scenario is actually a need for more sleep, not less.

The System of Sleep

In order to understand this counterintuitive reasoning, let’s start with little background on how this whole system of sleep works.

About three hours prior to when we’re naturally prone to waking up, our bodies start secreting a hormone called cortisol.

Cortisol is a stimulating hormone and is produced in times of stress in order to elevate the heart rate and stimulate the nervous system, but in the morning, it’s just trying to get us started. Think of it as mother nature’s caffeine.

And if cortisol is our morning cup of coffee, melatonin is our evening glass of wine. Once the sun starts to go down, our bodies recognize the onset of night and begin to produce this lovely sleep- inducing hormone, which helps us get to sleep and stay asleep until morning, when the whole process starts over again.

Overall melatonin production is increased and initiated earlier in the evening on the days that we get plenty of natural, nice, bright sunlight.

These Wacky Hormones and SLEEP

But as beautifully crafted as this system is, it’s not perfect and it’s easily confused. So in the situation we examined above, here’s what’s happening…

If your little is taking great naps during the day (this is obviously wonderful) and she’s getting lots of time outdoors, her body is ready to crank out some melatonin when nighttime rolls around.

So what’s with that burst of energy right before bedtime? When baby’s body has begun producing melatonin, there’s a narrow window of time when the body expects baby to be going to sleep. After all, she’s a baby. What’s she got to stay awake for? She doesn’t watch Tiger King and she hasn’t discovered TikTok yet.

The brain instinctively decides that something isn’t right since she’s stayed up beyond the natural melatonin window. Baby’s system starts secreting cortisol and, before you know it, she’s a little bit cranked.

This often shows up in the form of playfulness and an abundance of energy. In short, baby missed the sleepy window and now she’s going to have a hard time getting back to that point, but her behavior indicates anything but sleepiness.


If this is surge of cortisol is happening in your house, bedtime probably looks & feels like this!

So What Does All of This Have to do with Trying to Sleep Past 4 am?

Here’s what happens… Assuming your baby’s circadian rhythm is scheduling a 7 am wake up, then her body starts to secrete cortisol three hours prior to that. At this point, the melatonin production has ceased for the night.

So baby hits the (natural and normal) end of a sleep cycle around 4 am. She gets to that “slightly awake” state, and now there’s a little bit of stimulant (cortisol) and no natural sedative (melatonin). This, combined with a lack of independent sleep skills, means that baby’s probably going to wake up fully, and have a really hard time getting back to sleep.

So now for the big question you’ve probably been hoping I might have an answer for.

How do You Get Your Family to Sleep Past 4 am?

As I mentioned before, natural light during the day is the big cheerleader for melatonin production at night. Getting outside for natural sunlight is one way to encourage melatonin production and get a better night sleep.

It also helps to ensure that all sleep sanctuaries (aka bedrooms) are as dark as you can get them, and start turning down the lights in the house at least an hour before starting bedtime. Simulating the sunset will help to cue that melatonin production so that it’s in full swing when bedtime routines are complete. This is especially important in the summertime, as daylight hours extend later and later into the night! macbook-606763_640

Avoid any TV, iPhone, tablet, or screen time of any kind for that same hour (preferably even longer) before bedtime as these devices emit a geyser of blue light, which will stimulate cortisol production right at the time when you’re trying to avoid it AND prevent melatonin production right at the time that you (or your littles) really need it. That is double trouble!

Another factor often overlooked when it comes to early morning wakes is daytime sleep. Is your child getting enough for their age? Or are they a chronic short napper, sleeping only 20-45 minutes at a time? Getting too little daytime sleep will cause raised cortisol levels and often impacts nighttime sleep. If this sounds like your situation, head to our Crap Nap blog post to learn more.

But above all, the number one way to help your family sleep through the night and sleep past 4 am is to get everyone on a predictable, consistent and appropriate sleep schedule, and to teach the skills they need to fall asleep independently.

Teach Your Family to Become Independent Sleepers

The bottom line is we all wake up in the night, regardless of our age. As adults, we (well, most of us) have the ability to calmly assess the situation when we wake up in the dark, realize where we are, see that it’s still nighttime, and go right back to sleep. Most of the time we don’t even remember the wake up the next morning.

So although we can’t prevent your littles from waking up at night, studies show we can safely and effectively help everyone to  learn to recognize that they are comfortable, in familiar territory, still tired, and capable of getting back to sleep on their own. There are solutions to your child’s sleep struggles.

The guide will walk you step-by-step through what you need to do to put an end to them (and all of the reasons behind why they happen), and finally get your early mornings back.
