Potty Training Underwear - 6-Pack - Tiny Potty Heroes 🍼

They’re the result of real work, built hand-in-hand with hundreds of families 👇

✅ Dozens of back-and-forth improvements

We tested, adjusted, retested… every stitch, every centimeter, every layer.
Nothing was left to chance.

💧 Absorption refined down to the millimeter

We compared more than 11 brands.
While most rely on a single cotton layer that leaks after the first pee, we developed 5 smart layers, including organic bamboo, the most absorbent natural fiber.
Result: 3x more effective.

🌿 Materials chosen with intention

Organic bamboo, natural cotton, zero toxic substances. Many parents told us their children experienced redness and irritation with cheap training underwear… so we chose to go in the complete opposite direction.

🎨 Designs that tell a story

We worked with a French illustrator: every pattern is exclusive, and each one hides our tiny signature character.

👨‍👩‍👧 Hundreds of families involved

Spending a few dollars less on underwear that leaks is actually spending more: repeated disposable diapers, wet clothes, delayed potty progress…

Ours work. They last. They support your child all the way to full independence, without compromise.

Yes, your child can absolutely sleep in our training underwear, they’re comfortable and absorbent enough to handle small nighttime accidents.

👉 However, if accidents are still frequent or more substantial, we created a dedicated night-time range: built with extra absorbent layers, it provides calmer, more secure nights during the learning phase.

Yes, training underwear will absolutely help your little one use the potty. Once they have a small accident, they’ll clearly feel it (just like they do with pee) which is essential for building awareness.

If an accident happens:

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

With these simple steps, potty training becomes easier, smoother, and more effective 🐻

Our training pants are super easy to care for, just machine wash at 85–105°F (30–40°C) 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.

At Tiny Tots Undies, we do everything we can to make your experience simple and worry-free 💛

Exchanges are completely free — we cover both the return and the shipment of the correct size.
