Milk Lover (0-4m)

Bif and Bacteroides are seeded from Mom
  • Bifidobacterium dominated
  • Often high unfriendly bacteria is okay
  • Low amounts of food-associated bacteria
  • Low levels of diversity is normal

Baby on the Move (5-9m)

Baby’s first solids! Followed closely by gross solid poops
  • Still Bifidobacterium dominated
  • Unfriendly shouldn’t be very high anymore
  • Some amounts of food-associated species
  • Diversity increases as baby starts exploring

Solid Adventurer (9-12m)

You introduce more solids. They get more and more bacteria!
  • Here’s where we often see Bif no longer king, instead diversity is on the up and up
  • Food-associated bacteria are on the rise,  and we want to see diversity up, too
  • Baby’s gut is starting to look like a thriving toddler

Confident Eater (1-2y)

Maybe weaning, maybe not. Each journey’s different
  • Bifs are still lingering, but they’ve had their time
  • Baby’s microbiome is starting to share more and microbes with parents’
  • Now diversity is critical to good digestive health

Energetic Toddler (2-3y)

Your baby’s gut is now harder to throw off balance
  • Baby’s gut is stabilizing - it’s changing less
  • Now diversity rules the gut with food-associated bacteria moving in to stay
  • Good eating habits and the right bacteria will set your baby on track

Your child's gut can change as much as your child does

While your child continues to change and adapt their diet, lifestyle and environment. Many factors can disrupt the gut with unwanted side effects such as poor immunity, digestive issues, allergies, eczema, and more.

Your gut changes as much as your family does

Life isn't always predictable. Changes to your environment or habits may not only have a major impact on your lifestyle, but could cause potential disruptions to your gut. Stay on top of your family's health and keep side effects such as poorer immunity, digestive issues, and chronic illnesses in check.

"No other testing company was able to detect this strain"

My grandson and I both took the same strain of B. infantis and we were the first consumers to have this strain detected in our Tiny Health gut test. No other testing company was able to detect this beneficial strain, which completely turned around my grandson's gut from extremely inflammatory to anti-inflammatory. It also reestablished a healthy amount of bifidobacteria in my gut. Thanks, Tiny Health!

HIGHLY RECOMMEND!! This is an incredible service that I think every parent should take advantage of regardless of the age of your child. My son didn’t have any major concerns, but I wanted to make sure I was doing everything I could to set him up for a healthy future. After getting my report back it turned out there were quite a few things we needed to address.
K.K
The biggest takeaway from my consultation call was to focus on strategies to increase beneficial bacteria rather than get rid of unfriendly bacteria. We’re often so focused on getting rid of bad stuff, that the opposite might work better! I don’t think I would’ve come away with that on my own.
Alyssa F.
I am so grateful for the tool that is Tiny Health. I always want as much data as I can get when making decisions, especially for my young infant. With Tiny Health I was able to get data driven answers for my child. The action plan was very user friendly and I could quickly implement the recommendations to help my child! I would definitely recommend trying Tiny Health!

The first gut test designed with families in mind

Tiny Health was founded by Cheryl, a Mom looking to heal her baby’s microbiome after a C-Section birth. Unable to find clear, reliable answers anywhere she quickly realized that the only gut microbiome tests on the market were designed for grown-ups, not babies, leading to inaccurate results. She set out to create the first ever test to measure the microbiome health of babies during the critical first 1,000 days of life

Frequently asked questions

Can I use my HSA/FSA benefits to pay for Tiny+?

Many of our members use their FSA/HSA to pay for clinical fees and tests.

However, we recommend checking with your FSA/HSA company/carrier for information on what details are required.

In case there is any additional documentation you need, feel free to reach out to us at customer support, we’re more than happy to help you with the necessary paperwork.

Why should I join? Why do I need to test my baby multiple times?

During the first 1,000 days of a baby’s life, a type of programming takes place. This programming helps to determine a child’s lifelong health and has been directly linked to a wide range of metabolic and immune mediated disorders that fit under the umbrella of chronic disease, sometimes referred to as noncommunicable disease or noninfectious disease. And because of something called epigenetics, programming can even be carried from one generation to the next.

During a baby’s first 1000 days, you have the opportunity to make a big impact in everyday ways, like simple lifestyle or diet shifts.

As a baby grows, their gut matures and their immune system gets a little more skilled at identifying friend versus foe. Gut maturity is marked by diversity. After birth, the first major leap we see is when a baby begins eating solid food.

We recommend testing the first time to get a baseline of their gut, and then at least one another time to see the changes in how their gut has shifted. During the first 1,000 many things can cause shifts in the baby's gut fairly quickly including starting solids, introducing more foods, formula feeding, antibiotics, recovering from sickness, introduction to daycare and more. Seeing how their gut has shifted can help you make the most impact on your baby's gut during this critical period.

Please visit our Help Center for any questions we may not have answered here.
