6 reasons why July babies are special, according to science

If you've got a due date this month you can expect a baby with a sunny personality.

If you're preparing to welcome a little firecracker of your own this month, there are plenty of reasons to celebrate. For starters, you have already proven to be a tough mama by enduring pregnancy during the hottest month of the year in the northern hemisphere.

Here's why July babies are so amazing:

They look on the bright side ☀️

The weather isn't the only thing about July that's sunny: Research has shown that people born this month tend to have sunnier outlooks on life. The "hyperthymic temperaments" most commonly found among spring and summer babies mean they are prone to "excessive positivity"—which, as they will tell you, is not a bad thing at all!

They are in good company

The month of July is named after famed Roman leader Julius Caesar—whose birthday is attributed to July 12 or 13—but he's not the only influential person who celebrated a birthday in July. Other notable July babies include Nelson Mandela (July 18), Princess Di (July 1), Jackie Kennedy (July 28) and four past presidents (John Quincy Adams, Calvin Coolidge, Gerald Ford and George W. Bush).

They are good at regulating their emotions—even from a young age

According to a study out of Japan, babies born in the summer showed more "effortful control" than their autumn or winter peers by the age of 18 months. This refers to their "ability to voluntarily choose a course of action under conditions of conflict and to plan for the future and detect errors." And more effortful control is closely linked with greater emotional and behavioral regulation skills.

They are going to need perseverance

Studies have shown that babies born in the summer months are less likely to pursue higher education degrees. Experts theorize this link is due to the fact that summer babies are usually the youngest in their classes. But, as our naturally optimistic July babies would surely argue, that just means they are going to need a bit more perseverance!

They are the tallest in class

Brace yourself, mama: Babies born this month (as well as in June and August) have greater average birth weights. From there, they tend to go on to be taller than people born in other seasons.

They are more likely to be left-handed

Studies have shown that babies born between March and July are "significantly" more likely to be left-handed. As for the reason why? Researchers hypothesize it has something to do with "seasonal variation in other factors such as the incidence of infectious agents."

There you have it, mama! Coping with pregnancy during the sweltering summer months has its perks with your July baby—as your little optimist will kindly remind you later.

After 4 kids, this is still the best baby gear item I’ve ever purchased

I wouldn't be swooning over the BABYBJÖRN bouncer after eight years and four kids if it didn't work.

I have four kids 8 and under, so you might expect that my house is teeming with baby gear and kid toys.

But it turns out that for me, the more kids I have, the more I simplify our stuff. At this point, I'm down to the absolute essentials, the gear that I can't live without and the toys my kids actually play with. And so when a mama-to-be asks me what things are worth registering for, there are only a few must-haves on my list.

The BABYBJÖRN bouncer seat is on the top of my list—totally worth it and an absolute must-have for any new mama.

In fact, since I first splurged on my first BABYBJÖRN bouncer eight years ago (it definitely felt like a splurge at the time, but the five star reviews were really compelling), the bouncer seat has become the most-used product in our house for baby's first year.

We've actually invested in a second one so that we didn't have to keep moving ours from the bedroom to the living room when we change locations.

The utility of the seat might seem counterintuitive—it has no mechanical parts, so your baby is instead gently bounced by her own movements. In a world where many baby products are touted for their ability to mechanically rock baby to sleep, I get that many moms might not find the "no-motion" bouncer that compelling. But it turns out that the seat is quite reactive to baby's little kicks, and it has helped my kids to learn how to self-soothe.


Lightweight + compact:

The BABYBJÖRN bouncer is super lightweight, and it also folds flat in a second. Because of those features, we've frequently stored it under the couch, in a suitcase or in the back of the car. It folds completely flat, which I love.

Entertainment zone:

Is the toy bar worth it? The toy bar is totally worth it. Not only is the toy bar adorable, but it's one of the first toys that my babies actually play with once they discover the world beyond my boobs. The toys spin and are close to eye level so they have frequently kept my baby entertained while I cook or take a quick shower.

Great style:

This is not a small detail to me–the BABYBJÖRN bouncer is seriously stylish. I am done with baby gear and toys that make my house look like a theme park. The elegant European design honestly just looks good in my living room and I appreciate that parents can enjoy it as much as baby.

It's adjustable:

With three height settings that let you prop baby up to be entertained, or lay back to rest, we get years of use. And the bouncer can actually be adjusted for bigger kids and used from newborn to toddler age. It's that good.

It just works:

I wouldn't be swooning over the BABYBJÖRN bouncer after eight years and four kids if it didn't work. But I have used the seat as a safe space to put baby while I've worked (I once rocked my baby in it with my foot while I reported on a breaking news story for the Washington Post), and as a cozy spot for my second child to lay while his big brother played nearby. It's held up for almost a decade with almost-constant use.

So for me, looking back on what I thought was a splurge eight years ago, was actually one of the best investments in baby gear I ever made.

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."
