Why an uncomfortable gut means an uncomfortable night

The missing breastmilk  digester

Breastmilk contains complex sugars called HMOs that babies can't digest on their own — they're there to feed one specific bacterium, Bifidobacterium infantis. In many Western infants it's missing or low. When it is, those sugars pass through undigested.

Undigested sugars mean gas

Other bacteria ferment what B. infantis would have used. That fermentation produces gas — which for a small baby means pressure, discomfort, arching, and crying.

Discomfort disrupts sleep

A baby who's physically uncomfortable wakes more, settles harder, and is harder to soothe. No amount of routine adjustment resolves a physiological cause.

The first 1,000 days are the window

A baby's gut is at its most malleable in the first 1,000 days. Imbalances addressed early are easier to shift — and the same microbes that support digestion are also training their immune system.

Parents who stopped guessing about their baby's sleep

She had been sleeping through the nights and so happy since we decided to get her gut healthy with the information we received from our kit.

Tim P.

She's sleeping more and for longer stretches, she doesn't have horrible gas pains, and is spitting up much less.

Riley Winder

At 14 months old, he was sleeping more, talking, and responding more in general! I believe the probiotic made all the difference!

Frequently asked questions

What does a Tiny Health test look for?

  • A full breakdown of what we find in your gut microbiome
  • Key Insights about your gut microbiome and what they mean for your health
  • Condition Biomarkers, which may give you clues about what’s happening in your body and the risk for specific conditions
  • Associations between any symptoms you might have and your microbiome

How does testing work? What do I have to do?

We use an at-home stool test collected with a lab-certified swab from used tissue paper.

The process is simple and, unlike other tests on the market, Tiny Health doesn’t require gloves, a spoon-like collection device, or that you handle stool directly, just a regular tissue.

Store your sample in the included container and zippered bag, then mail it back to us in the prepaid envelope included with your kit.
