1 year of development—here's the full story ✨

They're the result of genuine hard work, created hand-in-hand with hundreds of families 👇

Dozens of iterations
We tested, adjusted, then tested again… every stitch, every centimeter, every layer. Nothing was left to chance.

💧 Absorption perfected millimeter by millimeter
Over 11 brands compared. Where they have a simple cotton layer that leaks at the first pee, we developed 5 intelligent layers, including organic bamboo—the most absorbent material. Result: 4x more effective, holding up to 200 ml.

🌿 Carefully selected materials
Organic bamboo, natural cotton, zero toxics. Because several parents told us their children had developed redness and spots with other cheap training pants… we decided to go in the opposite direction.

🎨 Designs that tell a story
We commissioned an American illustrator: each design is exclusive, with a little hidden character as our signature.

👨‍👩‍👧 Hundreds of families involved
We listened to your feedback, your concerns, your tips. This Version 2 is yours too: it was born thanks to you.

💸 A price that reflects all this work
Saving a few dollars on training pants that leak actually costs you more: repeated disposable diapers, wet clothes, delayed potty training. Our pants work. They last. They support you all the way to being dry, without compromise.

The trust that drives us
Today, over 10,000 families have chosen our training pants, with a rating of 4.9/5. And when we read your messages, we know we made the right choice by prioritizing quality, not the easy route ❤️

Gentle Nighttime Potty Training That Really Works 💤

Because every child deserves a gentle path to independence, our nighttime training pants are designed to teach, not just protect. Unlike noisy bedwetting alarms or disposable diapers that keep kids dependent, they encourage natural progress through subtle, science-backed cues:

💜 Smart absorbency that teaches awareness — Our 6-layer core absorbs accidents safely, while leaving a light sensation of dampness. This mild discomfort helps your child recognize their body’s signals and gradually stop wetting the bed.

💪 Building confidence overnight — Instead of feeling like they’re “still in diapers,” kids proudly wear real underwear, gaining self-esteem with every dry night.

👨‍👩‍👧 Peace of mind for parents — No more 3 a.m. sheet changes or stressful alarms. Just restful nights and confident mornings, knowing your child is making real progress.

Easy Care, Built to Last 200+ Washes  🧼

Tiny Tots Undies are simple to care for: machine wash cold (30–40°C) with a gentle detergent.

🌿 Skip fabric softener & tumble dry — let them air dry naturally.

💪 Lab-tested to stay soft, absorbent, and effective for 200+ washes.

👉 Always ready to support your child’s potty journey, night after night.

Free Returns. Risk-Free 60 Nights. 📦

How Does It Work?

Our night training pants combine 6 smart layers, grouped into 3 simple steps:

Gentle & Healthy Contact:

A first layer of hypoallergenic, breathable bamboo, REACH certified.
It quickly absorbs urine while leaving a slight feeling of dampness:

👉 a small discomfort that helps the child become aware of their needs.

High-Performance Absorbent Core

3 layers of microfiber that hold up to 10 fl oz of liquid (≈ the equivalent of 2 to 3 small regular diapers), while neutralizing odors.

👉 The children stays dry and odor-free, even in case of a nighttime accident.

Leak-Proof Shield & Comfortable Exterior

A waterproof membrane blocks leaks, even during a full night’s sleep or a long nap. On the outside, a soft and silent cotton finish provides the feel of real underwear.

👉 No discomfort, no plastic noise, just discreet protection.
