Yes — and the reason is simpler than you think.

Diapers are designed to keep your child completely dry. That is their greatest strength — and exactly the problem.

If your child never feels the difference between being dry and wet, their brain never builds the connection needed to learn to use the potty. It’s not their fault. It’s not your fault. The diaper is what prevents them from learning.

Why our training pants work where diapers fail:

Diapers absorb everything → your child never learns
Our training pants let them feel the moisture → awareness kicks in

Your child still feels “little” in diapers → zero motivation
In our training pants, they feel grown-up → they want to use the potty themselves

Diapers cost €50–80 a month, for months → wasted money
Our training pants are reusable → a one-time purchase

Here’s the point: diapers are designed to manage the problem. Our training pants are designed to solve it.

The problem with diapers is simple: they keep your child too dry to learn. Regular underwear, on the other hand, doesn’t provide enough protection and turns every accident into a disaster. Our training pants solve both problems at the same time.

The 3-layer system:
The inner cotton layer lets your child feel the moisture on their skin — that “I’m wet” sensation that diapers eliminate completely, but that is actually the signal the brain needs to learn.

The middle layer absorbs up to 3 times more than regular underwear, containing accidents without eliminating the sensation.

The waterproof outer layer protects clothes, sofas, and car seats — without taking away the sensory feedback that builds awareness.

The design:

Thin and featuring colorful patterns, they look like real underwear. Children want to wear them — and that’s already half the work. Very easy to put on and take off, they allow children to manage on their own, building independence and confidence with every small success.

Potty-training progress:

First week → your child begins to recognize the feeling of being wet, without unmanageable accidents
Second and third weeks → spontaneous requests to go to the potty increase
From the fourth week → potty use becomes increasingly consistent

In summary: diapers fail because they keep children too dry to learn. Regular underwear fails because it doesn’t provide enough protection. Ours do both — and finally, it works.

The honest answer: it depends on the child.

It would be great to give you a precise timeline, but every child is different — in age, personality, and previous attempts. Some parents report a breakthrough within the first few days. For others, it takes a few more weeks. Both are normal.

Usually:

First week → the child begins to recognize when they have wet themselves. It may not seem like much, but this is exactly where it all begins.

Second and third weeks → spontaneous requests to use the potty increase, and accidents decrease. This is often when “it clicks.”

From the fourth week → using the potty becomes the norm, rather than the exception.

What affects the timeline:

The child’s age and personality, previous attempts, and consistency in using the training underwear all play a part. More “stubborn” children often start more slowly — and then catch up quickly once they decide they want to do it.

The key difference:

With diapers, you wait and hope. With our training underwear, you actively build the awareness your child needs to succeed — from day one.

Most families see tangible progress within 2–3 weeks. But your child might surprise you sooner.

Most children want to wear these underwear. Here’s why:

They look like real underwear. They aren’t bulky like a diaper. They’re thin, colorful, and look (almost) like what Mom and Dad wear. Children notice that — and want to feel grown-up too.

The designs make all the difference. Colorful patterns, characters, bright colors. Not just another plain diaper, but something the child chooses and wants to wear.

They can put them on and take them off by themselves. Unlike with a diaper, the child doesn’t need anyone’s help. That little bit of independence means so much — they feel capable, and that feeling motivates them.

What if they still refuse?

Let them choose. Show them 2–3 different designs and let them decide. When a child feels that it’s their choice, resistance almost always disappears.

Use the right words. “These are your big-kid underwear, just like Mom and Dad’s” works better than any explanation.

Start gradually. Begin at the time of day when they’re most cooperative — often in the morning — and build from there.

Make it a special moment. Put away the “little-kid” diapers together and celebrate the new underwear — children love rites of passage.

Our 66-day guarantee covers exactly this scenario. If, after trying them, your child really doesn’t want to wear them, we’ll refund you in full. But honestly? It rarely happens.

Simple: our sizes are based on children’s actual body structure and therefore their weight. See our Size Chart.

• S: 3-9 kg
• M: 10-16 kg
• L: 17-25 kg

If you’re between sizes, choose the larger one — they’ll fit better and last longer.

Every order is covered by our 66-day guarantee. If the size isn’t right, we’ll exchange it for free — no hassle.

Yes. They are designed to last all night — they protect against wetness while still allowing your child to feel the moisture that supports learning. Potty training continues even while they sleep.

Yes, those too. For solid ones, just tip them into the toilet and toss the underwear in the washing machine. For more... challenging accidents, a quick rinse beforehand helps.

Either way, you’re covered.

💩 They handle the entire potty-training journey
🚽 Easy to clean
