Absorbs accidents

Designed using a dark coloured absorbent minky material and an added hidden layer of hidden microfibre, these undies will help absorb those little accidents while making your baby still feel wet. Unlike a diaper, these are not designed to hold a full pee, they will still keep your little one’s pants dry if they don’t quite make it to the toilet in time.

Grows just as fast as your littles

Fitted with both rise and hip snaps, our trainers are ONE SIZE, completely adjustable and will fit toddlers from about 20-45lbs (approx).That means these bad boys will be ready for you, no matter when your munchkin is ready to do the doo.

Leaks on Lock

Here at Lil Helper, we are nothing if not overachievers. So to really take the Zero-A Undies to the level of “over-the-top awesome” we added a layer of waterproof PUL. This way even small accidents will never be accidents.

Comfy for your little.

But not too comfy

These trainers are designed like underwear for independent use by your growing child. Our Zero-A undies stretch in all the right places. This makes them easy for your little one to pull up and down, while still containing any mess. Plus, the absorbent minky inner means the accident will be contained but your tiny human will feel wet and learn the steps of the bathroom boogie a little quicker.

With great power, comes great potential for mess.

Easy cleanup when 💩 happens

With most other trainers, when a #2 accident occurs, you would have to pull them down. This inevitably leads to a lot of smearing and turns a two minute cleanup into a full-blown bathtub operation. Our adjustable hip-snaps mean you can open the trainers up, remove them like a diaper, and save yourself some time and under-your-breath curse words.

Making a tough transition a little more intuitive.

Designed to be different than diapers

These trainers are not diapers. These are a transition tool designed to handle slip-ups, minimize mess, but still train towards the goal of Zero A. So they don’t pack enough punch to hold a whole pee because, once your child realizes they can go to town in their trainers, they will.

Nor are they the same as disposable trainers. Disposable trainers or Pull-ups allow your child to still use them as diapers as their goal is for you to buy them as long as possible.

We want you to use these for as little time as possible so your child becomes independent faster with as few frustration-induced tears (from you or your little) as possible.

Teaching another human how to, well, human requires the right gear and insane amount of patience. We’ve got you covered with the gear, and will say a prayer for patience to the potty gods in your name, promise.

Newbie Guide

Yes and no! These great undies are perfect for potty training kiddos to pull up and down on their own, however they are not meant to hold full blown pees. They are absorbent enough to avoid wet pants when our little ones have small accidents, however they are not made to hold a full pee.
Using both waist and rise snaps, they are completely adjustable from 20-45lbs.
Our Zero-A-Undies are not meant for overnight use, unless your little only has an occasional dribble in the night. If your kiddos are still having full pees throughout the night, these will not contain those floods! You may be able to add a booster if you are feeling creative, however this is not their intended purpose!

We do EC and these have been great since we are not 100% for pees. FOr a little extra, we add a bamboo booster (stay dry for when you want to stay dry, bamboo for when you want to feel it). If your kid has chubby thighs, they do fit on less than 20lb

I have to use liners with other brands I've used as my daughter is sensitive to the materials and breaks out in a rash. That makes pull up/down really difficult. She hasn't had that issue with these! And they hold really well :) Very happy with these!

Potty training sucks. It feels like a never ending uphill battle somedays. You know what doesn’t suck? These trainers! The PUL has saved my couch and the car seat more times than I can count. The lining holds just enough to keep back smaller accidents but still helps my son feel the wetness and know when to go. As a plus he’s obsessed with the shark week print and wants to wear it all the time so that one alone has reduced our accidents by print alone!


We’ve been fortunate enough to train two babies in these wonderful training pants. Even now, with two fully trained babies they are fantastic back ups for potential middle of the night accidents. I love that they are so much softer than the disposable pull ups and they are so much easier for my tiny people to get on and off.


We used to have a few mixed brands and hand me down bibs. After taking a chance on a biggie bib as an add-on, we fell in love! We’ve made the full switch, only carrying biggie bibs. We’ve used our daily for roughly 7 months so far and their still in great condition without staining (make sure to rinse asap with foods prone to staining).
Due to the large size, they really offer great coverage and keep my baby clean during my feedings. Would certainly say give it a try! You’ll love them.
