Babies. They are the cutest! With their little toes, chubby cheeks, perfect hands, and soft skin – it’s enough to make any mom or dad swoon. I think the reason we like babies so much is because they are so full of potential. Watching life unfold before the eyes of a child is a reminder of discovery and seeing amazement in the everyday. Let’s consider influences of baby microbiomes.  

The first understandings of how baby’s microbiome began was through the first introduction to beneficial bacteria via vaginal delivery, or a ‘bacterial baptism, as the vaginal tract is home to approximately 50 known bacteria.2 In instances where vaginal delivery is not an option, doctors have tried to recreate this introduction to mom’s bacteria through a technique called vaginal seeding. It involves taking fluid from the mother’s vagina and swabbing it over the nose, mouth, and skin of the newborn in an effort to protect the child from non-communicable diseases.5 As science progresses, we are able to learn more about baby’s microbiome and things that have an influence in on their micro microbiome.  

While babies are in utero, they rely on one source for all oxygen, nutrient exchange, waste removal, and life support: Mom. All these requirements cause lots of changes in mom. Those baby growing hormones contribute to heartburn, morning sickness (which, honestly, why is it called morning sickness? It knows no time restraints), things stretching in unbelievable ways, gorgeous supermodel hair, weird and temporarily delicious food combinations, increases in blood volume, brain fog, and crying at dog adoption commercials. Inside the microbiome, things are changing dramatically too. 

Between the first and third trimester, the maternal microbiome shifts in part due to the increases of estrogen and progesterone. Microbiome diversity in the first trimester appears to be similar to that of non-pregnant women. However, as pregnancy advances into the second and third trimester, a shift in diversity and an increase in abundance of gut bacteria associated with inflammatory states increases in nearly 70% of pregnant women.1,3 Interestingly, many of the changes that normally occur in the pregnant mama microbiome are actually comparable to metabolic syndrome outside of pregnancy, including the ratio of several key bacteria mimicking the higher levels of Firmicutes seen in obesity. 3 The thought is that the body is trying to prepare itself to consume more calories in order to grow another human, because that just takes an amazing amount of energy and effort on mama’s body. Anyway, if this shift to additional bacteria takes place under normal pregnancy terms, there are additional challenges when beginning with a gut with low diversity.  

Part of the reason why it’s important to see diversity as well as high numbers of good guys is because of the beneficial byproducts they kick off while digesting dietary insoluble fiber. Short chain fatty acids (SCFA) such as acetate, propionate, and butyrate are used by the intestinal epithelial cells (these are the important cells that act as a barrier between your insides and the outside world) as a source of energy for this tissue. SCFA production by the gut bacteria is associated with a healthy body mass index and leanness.3 So these are the good guy byproducts we like to see from our bacteria, pregnant or not. Having good numbers is important for mom and baby. 

Baby’s first microbiome influencer is always mama’s microbiome. Research continues to find more about the importance of mom having a healthy microbiome as it has a direct correlation to the diversity in baby’s gut. 1,2,4 This is great news because there are many good ways to influence baby’s microbiome before he or she even arrives in the world. Nearly all moms can strive to have high diversity and a good population of beneficial bacteria to share with baby, regardless of delivery method. 

If you are pregnant or thinking about becoming pregnant, check with your healthcare practitioner or doula to see if flourish or flourish Junior is a good fit for you. It’s like getting double the benefit – one supplement that helps you and baby! 

Parents work hard to equip their kids with the tools they need to be independent contributors to society. Parents put in the hard work helping with homework, instruments, practices, tutoring, flashcards, church events, social activities, and bake sales. We’re not perfect and make mistakes, but we do the best we can. Turns out, one of the best gifts you can give to your kids is a jump start in their microbiome. Pregnancy and delivery were their first dose of motherly love and bacteria.  Let’s continue to add to their microbiome as they grow from toddlers to high schoolers by supplementing with flourish and/or flourish Junior, eating fermented foods, and feeding both the kids and the bacteria with fiber-rich foods. Do you have a high schooler looking to the future with jobs or colleges? Take the time to teach them laundry skills and introduce them to their microbiome buddies. Who knows, maybe someday when they have kids, they will thank you for it.
