Soothe your baby's tummy for less fuss

No more helpless, fussy nights.

Your baby's crying may be a gut health issue. Time to try science-backed prebiotics and probiotics.

Soothe your baby's

My 5 month old baby would go sometimes 4 days without a bowel movement. This would really affect his mood, sleep, and he would have very uncomfortable gas pains and would keep us up all night long. Now he goes almost everyday and stopped suffering from painful gas! -Kamila K.

"I realized the key to lifelong health is how we begin."

"I realized the key to lifelong health is how we begin."

Madeline Lauf

Founder + CEO, Begin Health

I spent years struggling with my own gut issues, trying every "solution" and getting nowhere. The more I researched, the more I saw that adult health problems often have roots in early childhood.

I looked at options for kids and was shocked — most were filled with sugar and artificial fillers. Parents dealing with constipation were handed laxatives that never addressed the microbiome. Then I discovered HMOs: the prebiotics in breast milk, and the gold standard for human development.

So I assembled a team of nutrition scientists and researchers to bring that gold standard to every family — safe, evidence-based nutrition that gives kids the strong start they deserve.

Formulated with
the people
parents
trust most.

"A child's gut microbiome is almost entirely established by age three. Feeding it the right prebiotics early sets the foundation for lifelong digestive health."

Belinda Jenks, PhD, RD

Registered Dietitian · Scientific Advisor

"HMOs are one of the most exciting advances in pediatric nutrition — clinically shown to support the beneficial bacteria that keep digestion regular."

David Madsen, PhD

Microbiome Researcher · Scientific Advisor

"I see so many families stuck on laxatives. A prebiotic approach that works with the body — not against it — is exactly what most of these kids need."

Dr Gilberto Bultron, MD

Everything parents ask us.

How is this different from a probiotic alone?

Most probiotics just add bacteria and hope it survives. Beginbaby pairs a clinically-studied probiotic (B. Infantis + B. Lactis) with 2'-FL HMOs, the same prebiotic fiber found in breast milk, so the good bacteria has food to actually take hold and do its job and work harder.

How long until we see results?

Most families notice a difference in regularity, gas, and fussiness within 30 days of consistent use. Every baby's gut is different, so we recommend sticking with it through the full 30+ days before judging results.

Is it safe for daily, long-term use?

Yes. Beginbaby is formulated specifically for infants 0-12 months, with no sunflower oil, rice bran oil, maize starch, maltodextrin, silica, or carnauba wax. It's designed to be used daily, for as long as it's helpful for your baby.

Are the HMOs made from breast milk?

No; they're not extracted from breast milk. Our 2'-FL HMOs are produced through a fermentation process that creates the exact same molecular structure found naturally in breast milk, so your baby's gut recognizes and uses it the same way, whether they're breastfed, formula-fed, or both.

What if it doesn't work for us?

Every baby's gut timeline is different. If you don't see the changes you're hoping for after 30+ days of consistent use, reach out to our team at care@beginhealth.com. We're happy to help troubleshoot or talk through whether it's the right fit.

    Worth a try!

    My baby has been taking this supplement for 4+ months now. He has just now started to become "regular" so I honestly can't say that this is what helped or not.. however, this brand came highly recommend by his alt medicine provider at a time when he was having bouts of constipation. It is something I would reccomend someone try!

    Helped with my baby’s eczema!

    Eczema is a gut issue and I did so much research. Finally I took a stool sample test and it said my baby was missing certain strains of probiotics and recommended a pre/probiotic, this was one of the brands recommended. I loved how easy it was to just mix into his morning bottle. we started seeing results within a few weeks and within 3 months his eczema was completely gone!
