Yes — and the reason is simpler than you think.

Diapers are designed to keep the baby completely dry. That’s their strength — and it’s exactly the problem.

If the baby never feels the difference between 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. It’s the diaper that prevents it.

Why our training pants work where diapers fail:

Diapers absorb everything → the baby never learns
Our training pants let the moisture be felt → awareness is activated

The baby still feels "small" with diapers → zero motivation
With our training pants, they feel big → they want to use the potty themselves

Diapers cost €50–80 per 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 just one: they keep the baby too dry to learn. Regular underwear, on the other hand, doesn’t protect enough and turns every accident into a disaster. Our underwear solves both problems at the same time.

The 3-layer system:
The inner cotton layer lets the baby’s skin feel moisture — that sensation of "I’m wet" that diapers completely eliminate and that is instead the signal the brain needs to learn.

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

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

The design:

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

Potty training progress:

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

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

The honest answer: it depends on the child.

It would be nice 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 are wet. It may not seem like much, but this is exactly where it all starts.

Second and third week → spontaneous requests to use the potty increase, accidents decrease. It is often during this period that the "click" happens.

From the fourth week → using the potty becomes the norm, no longer the exception.

What influences the timing:

Age, the child's personality, previous attempts, and consistency in using the training pants all play a role. More "stubborn" children often start more slowly — but then catch up quickly once they decide they want to do it.

The key difference:

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

Most families see concrete 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 are thin, colorful, and look (almost) like the ones mom and dad wear. Kids notice this — and they want to feel grown-up too.

The designs make a 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 diapers, the child doesn't need anyone's help. That little independence means a lot — they feel capable, and that feeling motivates them.

What if they still refuse?

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

Use the right words. Saying "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 are most cooperative — often in the morning — and build from there.

Make it a special moment. Put away the "baby" diapers together and celebrate the new underwear — children love rites of passage.

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

Simple: our sizes are based on the actual body structure of children and therefore on their weight. Check our Size Chart.

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

If you are between sizes, choose the larger one - they will fit better and last longer.

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

Yes. They are designed to last all night — protecting against wetness while still allowing the child to feel moisture, which helps with learning. Potty training continues even while sleeping.

Yes, that too. For solid ones, just flush them down the toilet and put the panties in the washing machine. For more... challenging accidents, a quick rinse beforehand helps.

In any case, you're covered.
