The Toddler Constipation Struggle Is Real

If your toddler is dealing with constipation, you’re probably on the lookout for natural, gentle ways to help them go without relying on long-term laxatives. The good news? Science-backed fibers like chicory root inulin and human milk oligosaccharides (HMOs) are emerging as two of the most effective and well-tolerated ingredients to help symptoms associated with constipation in little ones.

Here’s why this dynamic duo is a game-changer for toddler gut health.

What Is Chicory Root Inulin?

Chicory root is a natural source of inulin, a type of soluble, prebiotic fiber. Prebiotics are fibers that don’t get digested. Instead, they feed the healthy bacteria in the gut, especially beneficial strains like Bifidobacteria.

Inulin helps:

  • Soften stool by drawing water into the colon

  • Improve gut motility

  • Increase stool frequency

  • Feed beneficial gut microbes

In a 2013 study, toddlers who took a combination of inulin and FOS (fructooligosaccharides) hadsofter, more frequent stools after 6 weeks of daily use [1].

What Are Human Milk Oligosaccharides (HMOs)?

HMOs are specialized prebiotics naturally found inbreast milk—with 2'-fucosyllactose (2’-FL) being the most abundant. They’renot digestible by humans, but they’re perfectly designed to feed the exact gut bacteria that babies need, especiallyBifidobacterium infantis.

HMOs support:

  • The growth of healthy gut bacteria

  • Softer, more regular stools

  • A stronger gut barrier and immune function

Even in formula-fed or older toddlers, supplementing with 2’-FL can mimic some of the gut health benefits of breast milk.

Why Toddlers Need Both

Most constipation solutions only tackle one angle: hydration, fiber, or stool softeners. But chicory root inulin and HMOs worksynergistically to support the gut from multiple directions:

Benefit

Chicory Root Inulin

HMOs (2’-FL)

Softens stool

Increases stool frequency

Feeds good gut bacteria

✅ (Bifido, Lactobacillus)

✅ (Primarily B. infantis)

Supports immune function

🔸

Gentle enough for toddlers

Together, they help build a gut environment that supportsnatural, regular pooping, not just quick fixes.

Where to Find Them

You can find both ingredients inGrowing Up Prebiotics, a tasteless, textureless powder designed for toddlers and kids 1 year and up. It’s easy to mix into:

  • Yogurt or applesauce

  • Milk or water

  • Smoothies or oatmeal

Parents consistently report better poop consistency and fewer tummy troubles after6 weeks of daily use.

Summary

For constipated toddlers, chicory root inulin and HMOs aren’t just hype—they’reclinically supported, naturally derived ingredients that help the gut work the way it’s meant to. When used consistently, they can reduce reliance on laxatives, soften stool, and build a healthier gut over time.
