Trainer (Training pants)

What are Trainers?

Trainers (training pants) are very similar to normal underpants and look like one at first sight. The difference lies in the fact that they are slightly thicker in terms of material and, above all, have an absorbent layer and also a waterproof layer.

Most trainers have a layer of waterproof PUL, which is either on the outside or sewn in hidden. The top layer is also usually made to give kids good wetness feedback. In between is a fairly thin, absorbent layer that provides leakage protection in case of "minor accidents."
Trainers are a good companion for potty training or when practicing diaper-free. When kids are growing up, the step to stop wearing ´nappies is a big one. But the road to getting there can sometimes be bumpy, and small setbacks often can't be avoided. With a trainer, the child is spared the embarrassment of having wet themselves and can proudly wear 'panties' already. In addition, parents do not have to change and wash all the clothes.

What do you need to know?

The wrong expectation: trainers are not a substitute for nappies! Many parents assume that trainers can be used similarly to nappies. However, since they only have a small amount of absorbent material, the child should already not need the nappies to some extent. A trainer cannot catch 'normal', a lot of pee.

The correct use of trainers: Trainers support your child in going to the potty or toilet independently. They reliably hold back minor accidents when the child is distracted or hasn't made it to the toilet or potty fast enough.

If your baby is still too young, can't walk yet, or still makes large amounts of pee, your baby then still need to wear nappies.

How many trainers and what accessories do I need?

1. Trainer:

Since trainers are used like regular pants, we recommend having at least 4-5 trainers on hand. If something goes wrong more often, it is worth having a few more pairs of underpants in stock.

To the trainers!


2. Potties and accessories

If your child can't or doesn't want to use the toilet yet, potties are a sensible purchase! In many Asian countries, a potty is part of every toddler's childhood and children even prefer to go potty all the time.

The child can also use the potty on its own and does not have to 'tell anyone'. This step towards independence and the self-determination that comes with it, is often a key to becoming dry.

Here you will find our potties and accessories..

3. Suitable clothing:

Dresses or long tops combined with leg warmer are great for the beginning. If the temperature is warm, you can leave your child naked at home, so that he or she gets a feeling for his or her own body even faster.

If it does have to be trousers, a comfortable waistband is helpful because it allows the trousers to be pulled down quickly.
