Brain Training Method in 3 Simple Steps

  1. Reset the Brain

    A tired brain has a hard time waking up. That’s why one of the simplest steps you can take—whether you order Super Undies or not—is to give your child an extra 30 minutes of sleep each night. This helps erase any sleep debt and keeps their brain from sinking into sleep that’s too deep to notice the bladder signal.

    When the brain is overtired, it also struggles to regulate vasopressin—the hormone that tells the body to slow down urine production at night.


  2. Light Up That Signal

    Disposables don't work. There’s no sense of “going,” so the brain doesn’t hear the pre-peeing signals responsible for waking a kid up. By switching to sensory underwear, you light up that signal with a full-on wet feeling—giving your now-reset brain the best chance of catching the pre-peeing tingling that happens.

  3. Prime the subconscious

    Have you ever had to wake up early for a flight and noticed you were already awake—or almost awake—before the alarm went off? That’s because you primed your subconscious with what you needed.

    The same thing can happen with your child. Having them talk to themselves about what they want—“to feel when they pee,” or “to know before they have to go”—is a powerful way to fast-track outgrowing bedwetting. Just make sure they speak kindly to themselves and give their body time to work it out.

    With these three steps, your kiddo is well on their way to overcoming bedwetting. This is how we take kids from wet nights and place them back into effective nighttime potty training—no matter how old they are. :)

Specifically Designed For Bedwetters

  • Outrageous absorbency included!  Comes with 1 built in liner and 1 extra liner that can change positions to cover your child's pee pattern. Need more soaking power? Just use another liner!
  • Reduce Landfill Waste and Never Buy Disposables Again
  • Leg locking gussets redirects wetness to the absorbent core
  • Waterproof guards at top of the tummy and back area redirect wetness back to the absorbency
  • Simple Washing Instructions Included
  • Brain Training Bedwetting Pants are made to order it the USA, in the colors of your choosing.


Leaks are not ideal and we work to mitigate them, however they do still serve the brain training method.

Preventing leaks requires a good fit and the right absorbency in the right place. For instance, a girl may need a Super Soaker Liner in the center of the trainer, like a maxi-pad, since girls pee centrally downward. While a boy may need an absorbency boost with a Soaker Bomb in the front of the training pant, since they saturate primarily at the front of their bodies. Super Undies Brain Trainers have been uniquely developed to customize the placement of absorbency, and to allow for the expansion of absorbency in the cases that require it. The majority of children do not need more absorbency beyond what is included with your Brain Trainers, yet it is possible for your child to pee more than the trainer can absorb.

The Flat Insert, included in every pair of Brain Trainers, can be placed in various areas that serve your child best. Check out the video above for expert placement advice!

Is this a bullet proof solution?

No, it may take support from you as the parent to troubleshoot on getting the right amount of absorbency in the right place. Our products have been tested for their absorbency capacity and is displayed on the image above for your reference.
