There's an antimicrobial compound in breast milk that could help formula-fed babies, too

Breast milk is incredible. We really don't need more studies to prove that breast milk has a ton of benefits for babies. We get it and we also get that breastfeeding isn't an option for everyone. But researchers are now looking further into the properties of human milk to figure out just how it works its magic because understanding what makes breastmilk great can help parents who feed their babies breastmilk, formula or both.

One recent study has identified a compound responsible for killing off bad bacteria, and their work might eventually help those who can't breastfeed their babies.

The study, published this month in the journal Scientific Reports, shows that human milk contains 3,000 micrograms per milliliter of a compound called glycerol monolaurate (GML). Cow's milk contains only 150 micrograms per milliliter of the stuff, and infant formula has none. Researchers from National Jewish Health and the University of Iowa then tested human milk, cow's milk and formula to see their effect on the growth of certain bacteria.

Compared to the other two milks, human milk was much better at stopping the growth of Staphylococcus aureus, Bacillus subtilis, Clostridium perfringens, and Escherichia coli—all of which can cause nasty infections and G.I. illnesses. (GML alone isn't very effective against Escherichia coli, a.k.a. E. coli, but the scientists believe it works in conjunction with other compounds in breastmilk to kill that bacteria.)

When the scientists then removed GML from the breastmilk, it stopped battling the harmful bacteria. And when they added GML to cow's milk, it successfully stopped the growth of Staphylococcus aureus. They also found that GML has anti-inflammatory properties, which is helpful in protecting babies' intestines and may be why breast milk is an effective treatment for atopic dermatitis.

"We think GML holds great promise as a potential additive to cows' milk and infant formula that could promote the health of babies around the world," Patrick Schlievert, PhD, professor of microbiology and immunology at the University of Iowa and the paper's first author, said in a press release.

So while GML is one more reason breastfeeding is awesome, this research is also getting us a step closer to helping the many children for whom that is not an option.

A very important letter for new mamas

Listen, mom-guilt is a dirty liar. Yes, it's your job to fill your little human's needs, but you matter too. Don't forget to take care of yourself. Hang out with friends, take a drive blaring 90's hip hop or shower without interruptions—trust me, you'll be a better person (and mom) because of it.

Dear new mom,

You will shave again someday. Today is not that day.

Set expectations low, my friend, and set your partner's lower—at least where body hair and overall hygiene are concerned.

That conversation could go something like this: “From now on let's not consider shaving a “standard," but more like a gift that happens on birthdays and the first day of summer."

Voila, you are a gift-giving genius. You know what else is a gift? Shaving the inch and a half of skin that is between your skinny jeans and your boots. You're welcome world.

You will not be perfect at parenting.

Boom.

I have yet to meet a perfect mother, but when I do, she's going to be a tiger who is insanely good at making up songs. (Daniel Tiger's mom, we salute you.)

I never wanted to be a mom. It wasn't something I ever thought would happen until I fell madly in love with my husband—who knew very well he wanted children. While he was a natural at entertaining our nephews or our friends' kids, I would awkwardly try to interact with them, not really knowing what to say or do.

Our first pregnancy was a surprise, a much-wanted one but also a unicorn, "first try" kind of pregnancy. As my belly grew bigger, so did my insecurities. How do you even mom when you never saw motherhood in your future? I focused all my uncertainties on coming up with a plan for the delivery of my baby—which proved to be a terrible idea when my dreamed-of unmedicated vaginal birth turned into an emergency C-section. I couldn't even start motherhood the way I wanted, I thought. And that feeling happened again when I couldn't breastfeed and instead had to pump and bottle-feed. And once more, when all the stress from things not going my way turned into debilitating postpartum anxiety that left me not really enjoying my brand new baby.

As my baby grew, slowly so did my confidence that I could do this. When he would tumble to the ground while learning how to walk and only my hugs could calm him, I felt invincible. But on the nights he wouldn't sleep—whether because he was going through a regression, a leap, a teeth eruption or just a full moon—I would break down in tears to my husband telling him that he was a better parent than me.

Then I found out I was pregnant again, and that this time it was twins. I panicked. I really cannot do two babies at the same time. I kept repeating that to myself (and to my poor husband) at every single appointment we had because I was just terrified. He, of course, thought I could absolutely do it, and he got me through a very hard pregnancy.

When the twins were born at full term and just as big as singleton babies, I still felt inadequate, despite the monumental effort I had made to grow these healthy babies and go through a repeat C-section to make sure they were both okay. I still felt my skin crawl when they cried and thought, What if I can't calm them down? I still turned to my husband for diaper changes because I wasn't a good enough mom for twins.

My husband reminded me (and still does) that I am exactly what my babies need. That I am enough. A phrase that has now become my mantra, both in motherhood and beyond, because as my husband likes to say, I'm the queen of selling myself short on everything.

So when my babies start crying, I tell myself that I am enough to calm them down.

When my toddler has a tantrum, I remind myself that I am enough to get through to him.

When I go out with the three kids by myself and start sweating about everything that could go wrong (poop explosions times three), I remind myself that I am enough to handle it all, even with a little humor.


And then one day I found this bracelet. Initially, I thought how cheesy it'd be to wear a reminder like this on my wrist, but I bought it anyway because something about it was calling my name. I'm so glad I did because since day one I haven't stopped wearing it.

Every time I look down, there it is, shining back at me. I am enough.

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."
