Your Nan Was Right All Along, Well... Almost
Everybody dreads the moment Nan starts in on potty training: “Back in my day...”
Believe it or not, she’s not wrong. For example, back in the 1950s, most kids were out of diapers before they turned 18 months.
Now granted, we don't agree with their "tough love" methods. But the nature of how things were back then did help them accelerate their timeline...
See, modern diapers & pull-ups are so good at hiding wetness that kids don’t even realize they’ve had an accident. And that’s a problem.
Because if they can’t feel it… they can’t fix it.
Luckily, child psychologists and pediatricians now agree on one thing: awareness is everything...
The Undies That Help Kids Feel the Accident — and Learn from It
Our training undies are built with soft cotton and a 6-layer absorbent core that catches small leaks, without hiding them completely.
That way, your little one stays just dry enough to avoid a mess, but still feels just enough wetness to cause mild discomfort, and learn what’s happening.
This is the key to faster, more confident potty training: natural cause and effect.
No soggy sheets. No plastic pull-up feel. Just real underwear that bridges the gap between diapers and independence, while making your toddler feel like a big kid.

What Other Parents Are Saying

Definitely keeping these around...
These are perfect! They're not a diaper - so get that idea out of your head that they will act in the same manner. They won't. BUT these are incredible because they look and FEEL like underwear so there is none of that confusion for my toddler. The quality is top notch. They are very heavy duty, true to size. You have to have other things in place to help your toddler be successful with potty training (like no drinks an hour before bedtime, going on the potty right before bed, etc). These will ensure you're not changing sheets every single day. other than that It's the perfect training underwear to help toddlers feel the "wetness".

Life saver!
My little guy was struggling with the popular pull-up disposables. They are just too close to diapers and didn't allow him to have the sensation of being wet. But once we switched to these we've had successful days of no accidents and no wet underwear. The colors and patterns are adorable, my 2 year old can effectively get them on and off with no help, they're easily tossed into the washer, super sturdy and catch all the little incidents (without leaking on the floor). I admit, a full bladder release might leave your little with some damp pants, but the underwear catches most of it.

Worked Well!
Currently potty training our toddler. I was skeptical to buy these for many reasons. The biggest one being, our toddler is on the higher side of the charts for height and weight. She wears a 6 - 8 at 2.5 years. I purchased a large size set and while they are a little big, they fit really well! They ride up high like a diaper which I like. They are SUPER absorbent! SUPER! The designs are so cute. The material is very comfortable and thick. I highly recommend these for potty training or kids with accidents / leaks. AND 💩 washes off of it SOOO easy!! In my opinion, these are worth every penny!
