Absorbs Accidents
Designed using a dark-colored, absorbent, minky material and an added hidden layer of microfiber, 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. But 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 potty training pants are ONE SIZE, completely adjustable, and will fit toddlers from about 20-40lbs (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.

Most users report that 4-6 Zero-A Trainers are the sweet spot for their potty training needs. That said, the exact number can vary depending on your child’s readiness, your potty training method, and other factors. Like most reusable products (and, let’s be real, most parenting choices), we recommend starting with 1 or 2 to see how they work for you and where your kiddo is on their potty training journey before committing to a full stash.
We recommend unsnapping the waist snaps or turning the undies inside out. For small accidents, you can toss them in with your regular laundry! Use a commercially available detergent, but skip the fabric softener and dryer sheets, and avoid hot water—it can damage the PUL. To dry, simply hang them up and let them air dry.
Yes and no! Zero-A undies are great for potty training because they’re easy for kids to pull up and down on their own. They’re absorbent enough to prevent wet pants during small accidents, but they’re not designed to hold a full pee. This helps your child learn to recognize wetness, which actually speeds up potty training compared to disposable pull-ups. Find out more about why we designed them this way here.
Maximum hip circumference: 22 inches (56 cm). Using both waist and rise snaps, they are completely adjustable to fit toddlers from 20-45 lbs (9-20 kg).
Our Zero-A Trainers are made of 4 main components: a stretchy cotton band for the best fit on your growing toddler, waterproof PUL to block leaks, a dark-colored absorbent minky that hides stains and helps your child feel when an accident is starting, and a layer of absorbent microfiber to protect your sofa/car seat as your little one learns.
Our Zero-A undies are not meant for overnight use unless your child only has occasional dribbles during the night. If your little one is still having full pees throughout the night, these won’t contain those floods! You might be able to add a booster if you're feeling creative, but this isn't their intended purpose. Find out why we designed them this way in this video.
