September is the most popular birth month

If you're expecting a baby this month you've got plenty of company. As many elementary school teachers have no doubt noticed, the first month of the school year is also the most popular month for birthdays in America.

The trend was first unearthed by data journalist Matt Stiles, who combed through birth stats from from the U.S. National Center for Health Statistics and the U.S. Social Security Administration collected between 1994 and 2014. He found that, statistically, mid-September is the most popular time to give birth—by far.

According to Stiles, the most common American birthdays fall on September 9, 19 and 12, respectively. Beyond that, nine out of the 10 most popular birth dates for babies in the United States are celebrated in September.

Just why are maternity wards so busy this time of year? The reasons aren't as clear as the data Stiles drummed up, but the calendar does provide some pretty good clues: Turn back nine months from September 9 and we're looking at December 17, a popular day for post-Christmas party canoodling and fireside snuggles. The conception date for a September 19 birth would be December 27, a day often reserved for relaxing with one's significant other after chaotic Christmas schedules.

Studies show the popularity of Christmastime conceptions might have as much to do with biology as holiday vacation time. And, interestingly, Stiles found the days most popular for baby-making aren't popular for baby-having.

“The least-common birthdays in this dataset were Christmas Eve, Christmas and New Year's Day," he notes. “Dates around Thanksgiving aren't as common. July 4 is also at the bottom of the list."

Obviously some of the reasons for the Christmas slump are due to medical interventions—as inductions and c-sections are less likely to be scheduled on December 25. Apparently OBs don't mind working on Valentine's Day, though, because that's one holiday with a relatively high birth rate.

As popular as it is (the sixty-third most common birth date) V-day can't touch September 9 when it comes to the amount of love entering the world. Maybe we should add another holiday to the calendar to celebrate this yearly baby boom? We could christen September 9 “Baby Day" and everyone could take the day off—although stats show that may lead to the rise of another popular birth date. What's the date nine months after September 9?

I felt lost as a new mother, but babywearing helped me find myself again

I wish someone had told me before how special wearing your baby can be, even when you have no idea how to do it.

My first baby and I were alone in our Brooklyn apartment during a particularly cold spring with yet another day of no plans. My husband was back at work after a mere three weeks of parental leave (what a joke!) and all my friends were busy with their childless lives—which kept them too busy to stop by or check in (making me, at times, feel jealous).

It was another day in which I would wait for baby to fall asleep for nap number one so I could shower and get ready to attempt to get out of the house together to do something, anything really, so I wouldn't feel the walls of the apartment close in on me by the time the second nap rolled around. I would pack all the diapers and toys and pacifiers and pump and bottles into a ginormous stroller that was already too heavy to push without a baby in it .

Then I would spend so much time figuring out where we could go with said stroller, because I wanted to avoid places with steps or narrow doors (I couldn't lift the stroller by myself and I was too embarrassed to ask strangers for help—also hi, New Yorkers, please help new moms when you see them huffing and puffing up the subway stairs, okay?). Then I would obsess about the weather, was it too cold to bring the baby out? And by the time I thought I had our adventure planned, the baby would wake up, I would still be in my PJs and it was time to pump yet again.

Slowly, but surely, and mostly thanks to sleep deprivation and isolation, I began to detest this whole new mom life. I've always been a social butterfly. I moved to New York because I craved that non-stop energy the city has and in the years before having my baby I amassed new friends I made through my daily adventures. I would never stop. I would walk everywhere just to take in the scenery and was always on the move.

Now I had this ball and chain attached to me, I thought, that didn't even allow me to make it out of the door to walk the dog. This sucks, I would think regularly, followed by maybe I'm not meant to be a mom after all.

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."
