"We’d been looking for a real alternative for a long time, and we’ve finally found it! The fabric is very gentle on his skin, there hasn’t been a single leak since we started using it, and the savings compared with disposable diapers are impressive. Our son was potty-trained in just two weeks. We’re truly delighted with the results!"

"We had tried several solutions without success. With these training pants, everything became easier. Our daughter started naturally recognizing when it was time to go to the potty, which she never did with disposable diapers because she couldn't feel anything. It really changed everything for us."
Marie A. -
"Our son didn’t like the feeling of being wet, but with regular diapers, it didn’t change his behavior. As soon as we switched to these training pants, he started telling us when he needed to go to the bathroom. Everything became much more natural, and today, he’s potty-trained!"

Why do so many parents choose SENIUM instead of disposable diapers?
Why do so many parents choose SENIUM instead of disposable diapers?
The answer is simple.
Disposable diapers are designed to absorb moisture immediately so that your child always stays dry. Comfortable for everyday use, but this does not help them recognize the sensations associated with toilet training.
SENIUM training pants, on the other hand, are designed to support this stage by helping your child better identify these sensations and gradually associate them with the need to go to the potty.
Why does SENIUM make a difference?
With a disposable diaper
Moisture is absorbed immediately.
The child remains in their baby habits.
Diaper purchases need to be renewed every month.
With SENIUM
The sensations are more noticeable, supporting toilet training.
Its design resembles real underwear, encouraging independence and confidence.
Reusable, it allows you to make significant savings compared with disposable diapers.
The result?
Disposable diapers are primarily designed to keep your child dry. SENIUM training pants support them throughout toilet training while helping you reduce your diaper budget. That is why many families see progress much more quickly.
How does the Sentir pour Apprendre™ method work?
How does the Sentir pour Apprendre™ method work?
The Feel to Learn™ method was designed to support children as they learn to use the toilet through a simple, gradual approach.
Disposable diapers absorb moisture immediately so that children stay constantly dry. In contrast, traditional training pants offer little protection and can lead to leaks that make this stage more difficult for the whole family.
SENIUM training pants strike the right balance: they allow children to feel sensations related to moisture while providing appropriate protection against everyday little accidents.
The 3-layer Feel to Learn™ system
Soft cotton inner layer
Gently lets moisture through to help children recognize the sensations at the right time.
High-capacity absorbent layer
Holds up to 3 times more liquid than traditional training pants to help prevent leaks.
Waterproof outer layer
Effectively protects clothing and surfaces while supporting toilet training.
What to expect
First week
Your child begins to better identify sensations related to moisture, with few little accidents.
Weeks 2 to 3
Requests to go to the potty become more frequent, and accidents become less common.
From the 4th week onward
Using the potty gradually becomes part of the daily routine.
In summary
Disposable diapers prioritize a constant feeling of dryness, while traditional training pants often offer limited protection. SENIUM training pants, combined with the Feel to Learn™ method, bring together the best of both: supporting toilet training while effectively protecting against everyday little accidents.
Is it really a good investment?
Is it really a good investment?
One purchase with SENIUM, compared with expenses that recur every month for disposable diapers.
At first glance, disposable diapers may seem economical. However, when you add up the purchases week after week, the cost quickly rises without you really noticing.
Every month, you have to buy more packs of diapers. The longer toilet training lasts, the more these expenses add up.
SENIUM training pants work differently. Reusable, they support your child on the journey to toilet training while gradually reducing the need to buy disposable diapers.
Do the math.
In just a few weeks or months, many families spend more on disposable diapers than the total cost of a set of SENIUM training pants.
Rather than paying for a purchase that has to be renewed constantly, you are investing in a reusable solution designed to support your child until they are toilet trained, while helping you save money in the long term.
When can we observe the first signs of progress?
When can we observe the first signs of progress?
Every child develops at their own pace.
There is no universal timeline for toilet training. Some children progress very quickly, while others simply need a little more time. The most important thing is to move forward step by step.
What families most often observe
First week
Your child begins to better identify sensations related to wetness and become aware of what is happening.
Weeks 2 to 3
Requests to use the potty become more frequent, and small accidents gradually decrease. This is often when parents notice a real change.
From the 4th week onward
Using the potty gradually becomes part of the daily routine, with greater independence and confidence.
Why does SENIUM make a difference?
Unlike disposable diapers, which keep children constantly dry, SENIUM training underwear encourages greater awareness of sensations while providing appropriate protection. It therefore supports your child from the very first stages of toilet training.
In summary
Most families observe progress within 2 to 3 weeks, although some children show signs of development within the first few days of use. Every journey is unique, but what matters is that your child progresses at their own pace with a method designed to support them.
What should I do if my child doesn’t want to use the potty?
What should I do if my child doesn’t want to use the potty?
Rest assured, this reaction is very common.
Many parents tell us that their children quickly take to SENIUM training pants. Several factors explain this enthusiasm.
Why do children like them so much?
Real big-kid underwear
Unlike a traditional diaper, SENIUM looks like real underwear. Wearing underwear “like grown-ups” naturally boosts a child’s confidence and motivation.
Patterns they love
Colorful prints make potty training more fun. Children are often eager to choose their favorite pair and wear it.
More independence every day
Easy to pull on and take off, SENIUM training pants help your child become more independent. The feeling of doing things “all by themselves” is often a great source of pride.
A few tips to encourage them
Celebrate this new milestone
Present SENIUM training pants as a symbol of growing up. The more positive this transition is, the easier it is to accept.
Let them take part
Offer several colors or patterns and let your child choose. Involving your child in the decision often strengthens their desire to wear them.
Take it gradually
Start during times when your child is most receptive, such as after waking up or before nap time, to establish a reassuring routine.
Celebrate every small victory
Make this new milestone a positive experience: praise their progress, use a reward chart, or turn each success into a small celebration. An encouraging approach is often the best ally in learning.
How do I choose the right size?
How do I choose the right size?
For the best fit, refer primarily to your child's weight. Our sizes are designed to fit toddlers' body shapes.
S: 3 to 9 kg
M: 10 to 16 kg
L: 17 to 25 kg
Between sizes?
We recommend choosing the larger size to give your child greater comfort and better freedom of movement.
Are SENIUM briefs suitable for nighttime use?
Are SENIUM briefs suitable for nighttime use?
Yes. SENIUM training pants provide effective overnight protection to help your child sleep comfortably while supporting their potty-training journey.
Thanks to their multilayer design, they reduce the risk of leaks while allowing your child to better perceive sensations associated with wetness.
Our advice for the first few nights:
During the training period, we recommend using a waterproof mattress protector to protect the mattress and approach this transition with peace of mind.
What happens in the event of an accident involving stool?
What happens in the event of an accident involving stool?
No worries, it’s part of the learning process.
In the event of an accident, simply remove the stool in the toilet, quickly rinse the underwear in cold water, then machine-wash it with your usual laundry.
If necessary, a light prewash will help remove any residue before the wash cycle. SENIUM underwear is designed for easy everyday reuse.
Our advice:
For optimal protection, make sure you choose the right size. The underwear should fit snugly around the thighs to help reduce the risk of leaks while remaining comfortable for your child.

Approved at daycare and potty-trained in 2 weeks
I bought 5 for my daughter. She wore them to daycare starting Monday, along with spare ones. The childcare workers were delighted: the little accidents were contained, and there were no soaked clothes. By the second week, there were no more accidents. She is so proud of herself.

Months of struggle, and then it worked.
I struggled for MONTHS and spent a fortune on diapers. In less than a week with Grandi training pants, my daughter was potty trained. She now wears real big-girl underwear. I still can't believe it. Honestly, I should have tried them much sooner.

The breakthrough in just a few days
Top quality, and my son loves the designs. They absorb well while still allowing him to feel the moisture—that’s exactly what makes the difference. It clicked within a few days. He goes to the potty by himself now. I’m ordering some for my daughter too.
