This new finding about why babies move so much in the womb is fascinating

As any pregnant mama knows, babies do a whole lot of moving around in the womb—usually in the middle of the night when we’re trying to sleep. As the weeks go by, those jabs and kicks start feeling stronger.


It turns out, though, the purpose on baby’s end isn’t just to get in a workout session, but to actually send vital signals that will help his or her body continue to develop properly.

According to a study published this month in the journal Development, kicks and movement stimulate molecular interactions that prompt the cells and tissues of the embryo to build a “functionally robust yet malleable skeleton.”

This means that kick may be telling the body it needs to have a bone covered in cartilage at the joint, or a jab over there may send the signal to increase bone strength.

For the study, researchers from Trinity College Dublin were able to control the fetal movements of chick and mice embryos. This gave them some interesting insight on what movements result in signals to boost cartilage or bone production.

“Our new findings show that in the absence of embryonic movement the cells that should form articular cartilage receive incorrect molecular signals, where one type of signal is lost while another inappropriate signal is activated in its place,” says co-author Paula Murphy, a professor in zoology at Trinity College Dublin, in a press release. “In short, the cells receive the signal that says 'make bone' when they should receive the signal that says ‘make cartilage.’”

These findings have cool implications not only for pregnant mamas thinking about what their babies are doing all day, but also for researchers seeking to improve treatments for joint injuries or diseases.

In other words, the movements are making babies stronger and healthier for when they’re born—and may help them decades down the road when researchers are better able to treat osteoarthritis.

Sorry, you can’t meet our baby yet

Thank you for understanding. ❤️

In just over three weeks, we will become parents. From then on, our hearts will live outside of our bodies. We will finally understand what everyone tells you about bringing a child into the world.

Lately, the range of emotions and hormones has left me feeling nothing short of my new favorite mom word, "hormotional." I'm sure that's normal though, and something most people start to feel as everything suddenly becomes real.

Our bags are mostly packed, diaper bag ready, and birth plan in place. Now it's essentially a waiting game. We're finishing up our online childbirth classes which I must say are quite informational and sometimes entertaining. But in between the waiting and the classes, we've had to think about how we're going to handle life after baby's birth.

I don't mean thinking and planning about the lack of sleep, feeding schedule, or just the overall changes a new baby is going to bring. I'm talking about how we're going to handle excited family members and friends who've waited just as long as we have to meet our child. That sentence sounds so bizarre, right? How we're going to handle family and friends? That sentence shouldn't even have to exist.

We are one and done—and we planned it that way

I didn't forget to have children. I just had a child. One child.

The other day, I saw a woman wearing a shirt that read, "Oops! I forgot to have children!" across the front, and I wanted to run up and give her a hug. Except that would be weird on many levels, so I buried the impulse.

I didn't forget to have children. I just had a child. One child. And lean in closer while I make this confession: My partner and I made that decision on purpose.

It's not really what I'd planned for myself when I was younger and daydreamed about my future family. In fact, I went through a phase in the '80s when I imagined myself with five children who I would name Mandy, Randy, Candy, Sandy and Andy.

I certainly never envisioned myself being any kind of spokesperson for the only-child crowd, but over my last 11 years, the most-asked question I get is whether or not I have regrets that we never gave my daughter a sibling.

That's a hard question because the number of kids you and your partner decide to have is an extremely personal decision—although you wouldn't necessarily know that by all the complete strangers who regularly ask, "So, when are you going to have another one?" or, "Don't you worry about what will happen to her when you die and she's left all alone in the world?" People, even well-intentioned, can be extremely insensitive and feel like they have the right to get in your business even if you just met them on an airplane.
