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 7 fl oz of liquid (= 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 illustrator to create exclusive designs, each 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 ❤️

All materials are REACH-certified, ensuring they are free from harmful substances and safe for your child’s skin 🌱

Science-Backed Potty Training Support 🚀

The first layer:

🌱 Buttery-soft bamboo fabric, naturally gentle and REACH certified, keeping your child comfortable and irritation-free while building potty awareness.

The absorbent core:

💧 2 smart layers engineered with microfiber technology that hold up to 7 fl oz of liquid (= 200 ml), managing small accidents while still allowing your child to feel wetness and recognize potty signals.

The outer layer:

🛡️ Breathable, water-repellent cotton shell prevents leaks during playtime and outings, while feeling and fitting just like real underwear.

Potty trained in 3 weeks — really? 🧐

Yes. Learn potty training in weeks, not months.

Tiny Tots Undies Training Pants help your child feel wetness, which activates body awareness and speeds up potty learning — without stress or pressure.

Give your little one the best chance of success:

Potty progress up to 73% faster compared to traditional methods

🌎 Zero disposable diapers = less waste and a greener habit

Can my child sleep in them? 💤

Yes — your child can sleep in our training pants.

They’re soft, comfortable, and absorbent enough to handle small nighttime accidents.

👉 However, if accidents are still frequent or larger during sleep, we recommend our Overnight Training Pants, designed specifically for nighttime needs. With additional absorbent layers, they offer up to 12 hours of protection for worry-free nights.

About poop 💩

Yes, training pants will also help your little one learn to poop on the potty.

If they have an accident, they’ll clearly feel it, just like with pee, which helps them understand and learn faster.

If an accident happens:

  1. Empty the solids into the toilet
  2. Wash as usual with your regular detergent

With the right routine, potty training becomes easier, calmer, and more successful 🐻

How do I wash the Training Pants? 🧼

Our training pants are easy to care for — just wash them in the machine at 30–40°C (85–105°F) with a gentle detergent.

To protect absorption and the waterproof layer:

❌ Avoid fabric softener

❌ Avoid the dryer

Instead, air-dry them (after a quick cold-water rinse if needed) to keep them soft, absorbent, and long-lasting.

Wrong size? We’ve got you : free exchanges 🌈

If the size isn’t a perfect fit for your little one, don’t worry.

We take care of everything: returns are 100% free, and we’ll send you a new pack in the right size at no extra cost.

Potty training should be stress-free — for you and your child 💛✨

gently and without pressure

Week 1: The breakthrough

Your child switches from diapers to training pants. They feel a light dampness after an accident

👉 that gentle sensation is the key signal that builds body awareness.

Week 2: Learning

You offer the potty regularly, without pressure. Your child starts connecting the feeling with the action.

👉 They begin to succeed, and their confidence grows.

Week 3: Independence

Your child begins to ask on their own and anticipate their needs. Accidents become rare.

👉 They feel proud, dry… and truly independent 🧸

How does it work?

Our training pants combine 5 smart layers, organized into 3 simple steps:

Soft and healthy contact

A first layer of hypoallergenic, breathable, REACH-certified bamboo. It quickly absorbs urine while leaving a light feeling of wetness

👉 a gentle natural cue that helps your child recognize their needs and build potty awareness.

High-performance absorbent core

Two layers of microfiber that hold up to 7 fl oz of liquid (= 200ml) while neutralizing odors.

👉 Your child stays dry and fresh, even when little accidents happen.

Leak-proof shield & soft outer comfort

A waterproof layer blocks leaks during playtime and outings. On the outside, a soft, quiet cotton finish gives the feel of real underwear

👉 No plastic noise, no discomfort, just discreet protection for confident movement.
