From Infant Sleep Regression to 11 Hours Through the Night
I recently had a client come to me right as her baby was approaching four months old, and she was nervous about one thing in particular: the 4 month sleep regression.
And honestly, I get it. Because imagine this…
You’re finally starting to get the hang of this whole new mom thing. You can change a diaper in the dark. You know which cry means hungry and which one means I’m tired but I’m going to fight you on it anyway. You’ve figured out how to leave the house with approximately 47 things just to run one errand. 😂
And sleep is actually starting to happen! Your baby is giving you longer stretches at night, naps are becoming a little more predictable, and you’re starting to feel like an actual functioning human again. You might even catch yourself thinking, Okay. I think I’ve got this.
Adorable. 😂
Because right around four months, your baby may decide it’s time to completely change the rules. Suddenly they’re waking more at night. That beautiful nap you were counting on? 31 minutes. You finally get them back down and 27 minutes later… hello again! Bedtime starts getting weird. Your baby is exhausted but somehow also VERY opposed to sleeping, and you’re standing there thinking, Wait. We had a system.
Welcome to the 4 month sleep regression!
And because changing their sleep wasn’t enough excitement for one month, your baby may also start rolling. Yay! Huge milestone! Except now it may be time to say goodbye to the swaddle. Of course. 😂 Maybe they’re also outgrowing the bassinet, so now you’re thinking about a crib transition too. They’re staying awake longer, noticing EVERYTHING, and their naps may be shifting. The ceiling fan is suddenly more interesting than sleep could ever hope to be.
Basically, your baby downloaded a massive software update overnight and nobody gave you the patch notes.
So naturally, you Google it. Why did my 4 month old stop sleeping? And Google introduces you to three words no tired mom wanted to meet: 4 month sleep regression. Now you’re reading about night wakings, short naps, changing sleep cycles and something that could potentially last for weeks or even months. 😩
Excuse me… Months?!
This was exactly what my client was worried about. She didn’t want to lose the progress they had made or spend the next month or two just waiting and hoping sleep eventually figured itself out.
And the first thing I wanted her to know was that yes, the 4 month sleep regression is real. But that doesn’t mean you have to accept months of terrible sleep.
There is SO much happening around four months. Your baby’s sleep cycles are maturing. They’re becoming more alert and aware of everything around them. They’re learning new physical skills, they’re able to stay awake longer, and their nap needs may be shifting. Sometimes several of these changes happen at basically the same time.
So the routine that worked beautifully a few weeks ago may suddenly… not.
And that’s incredibly confusing when you’re doing all the same things that worked before. But that’s also the clue. Your baby changed. Instead of trying harder and harder to make the old routine work, sometimes we need to figure out what this new version of your baby needs.
Then comes the part that can really make an infant sleep regression snowball. Your baby has a rough night, so they’re tired the next day. Then naps are a mess, so now they’re even more tired. Bedtime arrives and you’re thinking, This child is EXHAUSTED. Tonight is going to be amazing.
Your baby: Absolutely not. 😂
Bedtime gets harder. Maybe there’s a false start. Maybe they’re waking more overnight. Then you wake up the next morning with an even more tired baby and get to start the whole party again.
This is where I see a lot of families get stuck. What may have started as a developmental shift can quickly turn into accumulated sleep debt. Now it’s not just the original regression disrupting sleep. Your baby is tired, the day isn’t flowing quite right anymore, and nobody knows which problem they’re supposed to fix first.
This is where we got strategic with my client. Instead of thinking, How do we survive the 4 month sleep regression? we started asking a much more helpful question:
What does her baby need now?
Maybe the timing that worked three weeks ago didn’t fit anymore. Maybe naps needed to shift. Maybe her baby needed help catching up after some rough sleep. Maybe awake windows needed to change. Maybe there were several little things happening at once, which is often the case. 😁
The goal wasn’t to wait for some magical day when the regression was officially “over.” It was to pay attention to the baby in front of us and build the day around what she needed now.
And that’s the funny thing about calling this a “regression.” Your baby isn’t really going backward at all. They’re actually doing SO much growing. Their brain is developing, their sleep is maturing, they’re learning new skills, and they’re taking in more of the world around them.
They’re progressing. It just happens to look a little like chaos from your side of the crib. 😂
And that’s why I don’t want parents to hear the words sleep regression and immediately assume they’re doomed to weeks or months of terrible sleep. Sometimes your baby just changed the rules on you.
Rude? A little. 😂 But manageable.
And here’s my favorite part of this client’s story. We didn’t just get her baby “back on track.”
Her baby ended up sleeping 11 hours a night. 🙌
And here’s the part I really want parents to hear: this had nothing to do with self soothing. We did it through routine building alone. We figured out what her baby needed at this new stage, adjusted the day around those needs, and gave her the opportunity to get the sleep she needed.
So if you’re currently in the middle of the 4 month sleep regression, wondering what in the world happened to your great little sleeper, don’t panic. Your baby didn’t forget how to sleep. They grew. Their sleep changed. Their needs changed.
And sometimes what comes after a regression can actually be even better than what you had before.
In this case… 11 hours a night better. 😁
