How to use Trepanman for potty training

Trepanman is very useful for potty training!

You can use Trepanman to help you ask your child to go use the bathroom, and to help them realize when they have urinated a little.

You can say, "Let's find the same picture!"

It becomes an opportunity to get your child interested in the pants and in potty training. Changing what you say may make diaper changes go more smoothly.

Moony-chan asks your child to go use the bathroom!

If you use the potty training app and hold the phone up to the Trepanman reward stickers, Moony-chan will appear and ask your child to go use the bathroom.

When you see the alert sign, it's your chance to tell them!

Show your child the alert sign, say "You peed," and tell them that they urinated.

Please tell how "the wet feeling is".

If they urinated, say "It's wet, isn't it. This is pee." Smile and say, "Next time, tell me if you pee."

Encourage your child to draw or write their name on Trepanman

If the pants are unique and special, it will lead to your child feeling that they don't want to get the pants dirty, and that they want to go use the bathroom instead.

Use reward stickers to praise them

If they successfully use the toilet, have your child paste the reward stickers that come with Trepanman onto the sticker pages.

Praise them a lot, saying "Good job!" and "Amazing!"

Reviews from moms who actually used Trepanman

From Chiimame

He said the blue training pants looked cool and wanted to put them on himself, and he got very excited about the stickers on the back and the pictures of trains. Normally he wouldn't tell me if he peed, but he started reporting "I peed" after that.

From Erika

I used Trepanman when my oldest child was potty training. She liked Thomas and trains, but that was around the time that she started liking girly pinks, princesses, and flowers, so the packages were cute and put her in high spirits, which was helpful.

From Chiiyan

When Moony-chan asked her to go use the toilet, she started going! Normally when I would ask her to go, she said she hated it, so I was really impressed.

From Yuzumaru

I was doing potty training during the day when I was the only one there to watch him, and the app ended up being a strong ally. Moony-chan was cute and close by and would let me know, so it created opportunities for me to lead him to the bathroom. It made it easy to say "Moony-chan says you should go to the bathroom soon! Let's go together!" It made things go more smoothly and I was grateful that it made it easier and more fun to ask him to go use the bathroom. I think it was thanks to Moony-chan that I was able to get through it without the bathroom becoming a place that he hated.

From Kujira-kun's mom

They are easy to take off and put on. He seemed to be very interested in the stickers, which made it easy to praise him for using the bathroom and I felt that these made a really good reward. In the same way, he also enjoyed the different designs.

From Ringo-chan

If he peed, he told me quickly, so it seemed like he understood when it felt wet. I touched it to check, and I think it did feel really wet.

From Kyui-chan

There was more communication between my child and me during diaper changes, and he was able to enjoy potty training.

He looked forward to pasting the reward stickers, so he was able to work hard for that. He didn't hate diaper changes and looked forward to it instead, so that really helped me as a mom.

From Kurabu-kun's mom

Because there were reward stickers, he could visually see how hard he had worked, and this increased his motivation. The pants had different designs, so I could say "What will the next pants be? Let's go to the bathroom and look for them." And it became an opportunity to go to the bathroom.

From Tomato-chan's mom

There were stickers that children like, and she showed interest quickly. It felt wet when she peed in her diaper, so she would tell me "I peed." When I asked "Will you go to the bathroom?" she obediently went there, and she started wanting to go to the bathroom by herself.

From Sheru-kun

There were lots of things that made it easy for children to go to the bathroom (stickers, the drawing space, and designs), which also made it easy for me to ask about it. Example: I said "Why don't we go to the bathroom so you can stick the stickers?!" He said "I want to stick the stickers! I'm going!!" We also drew pictures on the pants together, and I said "The pants that you drew on, let's not get them sticky, OK?" He said "OK!" So both of us were able to spend a fun time in the bathroom.
