4-month sleep regression

So this is happening. It seems that my third child is officially carrying on the 4-month sleep regression tradition in our family. Our oldest daughter started us off, our middle daughter followed suit, and here we are with our third baby—in the throes of exhaustion. We thought we might be in the clear for a week or two, but not so much.

This “sleep interruption" as I'll call it, started right around four months. Our daughter started rolling, which was very exciting! But then she also started rolling over in her bassinet, which was confusing.

What do we do now?

Even though we've done this twice before, I honestly forgot. We remembered that we had to stop swaddling (which was sad because she liked that and it worked really well!) and we also had to say goodbye to the bassinet. It just seemed like she needed more room.

So, we pulled out the pack 'n' play, moved that into our room and tried her in there, in a sleep sack.

No such luck.

She was still rolling around with all the free space she had and was waking herself up every five minutes. I'd nurse her or bounce her and finally get her settled, then lay her down and boom—eyes wide open.

Waking up every 10 minutes or so is exhausting. This is also post-family winter sickness where sleep was interrupted plenty, so this new interruption is kind of a bummer.

The other night I was rocking my baby—my sweet and very tired baby—back to sleep, and as I was sitting there with her, I was googling "4-month sleep regression" trying to figure out where we were going wrong, or what I could be doing better, or why this was happening in the first place.

While I wish I could report all of those answers, I can't. I was falling asleep as I was reading and some of it stuck, but most of it didn't. Basically, their brains are maturing and their sleep cycles are becoming more adult-like. (Ah, they grow up so fast!)

So while the 4-month sleep regression can be frustrating and downright exhausting... it also means your little one's development is right on track—even if everyone's sleep schedules are totally derailed. (Yay!)

I can't tell you that dealing with the exhaustion and navigating this 4-month sleep regression is going to be fun (because sleep is fun and not sleeping is not fun) but I can you tell something: This too shall pass.

I know that's kind of annoying (and that may be the exhaustion talking), but it really is true. This is my third time watching a child do this.

My third time bouncing and rocking and trying to do everything to calm my baby who has woken up for the fifth time by 2 am.

The third time I'm trying to get our baby back to sleep when she seems interested in anything but.

The third time I've whipped out the magic Merlin sleep suit to try to help our tired baby. (Worth the try.)

And soon, it'll be my third time making it through to the other side. Because while this storm is a little dark and rocky—it's fast, and it's beautiful once you make it through.

The other side is filled with more rest, less anxiety and a happy, growing baby.

This season doesn't last forever—I know this because I've already seen it pass two other times. So hold on, because you're probably already *almost* there. And remember—just like with any stormy parenting period, they make you stronger and more confident—ready to take on whatever curve ball is thrown next.

Because you know it's coming, so get that glove ready.

In the throes of it, mama? Here are some products we love that can help.

Time-saving formula tips our editors swear by

Less time making bottles, more time snuggling.

As a new parent, it can feel like feeding your baby is a full-time job—with a very demanding nightshift. Add in the additional steps it takes to prepare a bottle of formula and, well… we don't blame you if you're eager to save some time when you can. After all, that means more time for snuggling your baby or practicing your own well-deserved self-care.

Here's the upside: Many, many formula-feeding mamas before you have experienced the same thing, and they've developed some excellent tricks that can help you mix up a bottle in record time. Here are the best time-saving formula tips from editors here at Motherly.

1. Use room temperature water

The top suggestion that came up time and time again was to introduce bottles with room temperature water from the beginning. That way, you can make a bottle whenever you need it without worrying about warming up water—which is a total lifesaver when you have to make a bottle on the go or in the middle of the night.

2. Buy online to save shopping time

You'll need a lot of formula throughout the first year and beyond—so finding a brand like Comforts, which offers high-quality infant formula at lower prices, will help you save a substantial amount of money. Not to mention, you can order online or find the formula on shelves during your standard shopping trip—and that'll save you so much time and effort as well.

3. Pre-measure nighttime bottles

The middle of the night is the last time you'll want to spend precious minutes mixing up a bottle. Instead, our editors suggest measuring out the correct amount of powder formula into a bottle and putting the necessary portion of water on your bedside table. That way, all you have to do is roll over and combine the water and formula in the bottle before feeding your baby. Sounds so much better than hiking all the way to the kitchen and back at 3 am, right?

4. Divide serving sizes for outings

Before leaving the house with your baby, divvy up any portions of formula and water that you may need during your outing. Then, when your baby is hungry, just combine the pre-measured water and powder serving in the bottle. Our editors confirm this is much easier than trying to portion out the right amount of water or formula while riding in the car.

5. Memorize the mental math

Soon enough, you'll be able to prepare a bottle in your sleep. But, especially in the beginning or when increasing your baby's serving, the mental math can take a bit of time. If #mombrain makes it tough to commit the measurements to memory, write up a cheat sheet for yourself or anyone else who will prepare your baby's bottle.

6. Warm up chilled formula with water

If you're the savvy kind of mom who prepares and refrigerates bottles for the day in advance, you'll probably want to bring it up to room temperature before serving. Rather than purchase a bottle warmer, our editors say the old-fashioned method works incredibly well: Just plunge the sealed bottle in a bowl of warm water for a few minutes and—voila!—it's ready to serve.

This is my one trick to get baby to sleep (and it always works!)

There's a reason why every mom tells you to buy a sound machine.

So in my defense, I grew up in Florida. As a child of the sunshine state, I knew I had to check for gators before sitting on the toilet, that cockroaches didn't just scurry, they actually flew, and at that point, the most popular and only sound machine I had ever heard of was the Miami Sound Machine.

I was raised on the notion that the rhythm was going to get me, not lull me into a peaceful slumber. Who knew?!

Well evidently science and, probably, Gloria Estefan knew, but I digress.

When my son was born, I just assumed the kid would know how to sleep. When I'm tired that's what I do, so why wouldn't this smaller more easily exhausted version of me not work the same way? Well, the simple and cinematic answer is, he is not in Kansas anymore.

Being in utero is like being in a warm, soothing and squishy spa. It's cozy, it's secure, it comes with its own soundtrack. Then one day the spa is gone. The space is bigger, brighter and the constant stream of music has come to an abrupt end. Your baby just needs a little time to acclimate and a little assist from continuous sound support.

My son, like most babies, was a restless and active sleeper. It didn't take much to jolt him from a sound sleep to crying like a banshee. I once microwaved a piece of pizza, and you would have thought I let 50 Rockettes into his room to perform a kick line.

I was literally walking on eggshells, tiptoeing around the house, watching the television with the closed caption on.

Like adults, babies have an internal clock. Unlike adults, babies haven't harnessed the ability to hit the snooze button on that internal clock. Lucky for babies they have a great Mama to hit the snooze button for them.

Enter the beloved by all—sound machines.

It's science: Why your baby stops crying when you stand up

A fascinating study explains why.

When your baby is crying, it feels nearly instinctual to stand up to rock, sway and soothe them. That's because standing up to calm babies is instinctual—driven by centuries of positive feedback from calmed babies, researchers have found.

"Infants under 6 months of age carried by a walking mother immediately stopped voluntary movement and crying and exhibited a rapid heart rate decrease, compared with holding by a sitting mother," say authors of a 2013 study published in Current Biology.

Even more striking: This coordinated set of actions—the mother standing and the baby calming—is observed in other mammal species, too. Using pharmacologic and genetic interventions with mice, the authors say, "We identified strikingly similar responses in mouse pups as defined by immobility and diminished ultrasonic vocalizations and heart rate."
