Tiny Liners – Boost Absorbency When You Need It Most!

Fits perfectly in all Fearless Training Pants!

Tiny Liners are the perfect way to add extra absorbency to your Super Undies™ Fearless Trainers when your child needs a little more protection.

Use 1 Tiny Liner for:

Starting Out:
When your child first switches from diapers to training pants, leaks can be surprising and uncomfortable. Adding one Tiny Liner helps catch small accidents while your child gets used to their new big kid undies.
On-the-Go Protection:
Headed to the park or a quick car ride? One Tiny Liner adds peace of mind without giving up the feeling of real underwear. Great for when you can’t get to a bathroom right away!

Real Parent Tip:
"My little one was potty trained at 25 months but still needed to pee every 45 minutes. Tiny Liners gave us confidence for car trips and outings—and saved us from embarrassing accidents!"

Use 2 Tiny Liners for:

Naptime:
Some kids pee right before waking up or as they stir from sleep. Two Tiny Liners provide extra protection during naps without needing to go back to diapers.
Early Potty Learning (Under 2 Years Old):
Not quite ready to ditch the diaper? Start with two Tiny Liners in your Fearless Trainers. They offer the same absorbency as a cloth diaper while gently helping your child feel when they’re wet—a key part of potty learning. As they get better at staying dry, you can reduce to one liner and build their potty awareness.
