We’re parents too. After struggling with diapers, confusing methods, and too many messes, we realized there was a better way. So we teamed up with pediatricians and designers to create training underwear that actually helps kids learn — instead of just managing accidents. Thousands of parents later… it’s still the product we wish we had from day one.

We’re not diapers. We’re not pull-ups. We’re not plastic.

TrainBuddies™ is real underwear that helps your toddler potty train faster — with fewer messes and more wins. 🚽

Feels like real undies (because they are)
💧 Absorbs small accidents without bulk
💪 Builds your child’s confidence
🧠 Supports popular methods like Oh Crap
🧺 Washable. Reusable. Eco-friendly.

We design our underwear with a triple-layer absorbent core that helps reduce leaks and messes. However, they’re not leakproof in the way a diaper is. If your child has a larger accident or wears them overnight, there may still be some leakage. These are best for daytime accidents during active potty training.

Just rinse (if needed), toss in the wash, and dry. They’re built to survive hundreds of washes — because, let’s be real, you’ll need them to.

🧼 Machine washable

♻️ Reusable + eco-friendly

👶 Still super soft after 100's of washes
Be sure to use a warm or cold wash, and delicate setting where possible!

TrainBuddies™ underwear is designed primarily for daytime training — where your toddler is awake, aware, and learning body cues. Nighttime dryness is a different journey, and most children take longer to master it. That said, many parents use TrainBuddies™ for night time and find success while transitioning out of diapers. For heavy night wetting, we recommend pairing with a waterproof mat or our extra inserts for extra peace of mind.

Made from premium fabrics and a waterproof outer layer, our TrainBuddies™ Training Underwear ensures a pleasant experience for your toddlers during potty training. These underwear feature six layers of eco-friendly materials designed to be gentle on the skin, provide maximum absorbency and protection, and include a leak-proof outer layer with fun, cotton designs. Here’s the technology infused in your favorite TrainBuddies™ Training Underwear:

• 
  : Crafted from high-quality cotton that is undyed and unbleached, making it safe for your child’s delicate skin. This cotton fabric is breathable and comfortable, helping to prevent skin rashes and protect against pollen, dust mites, and other allergens.
  
• 
  : These “absorbency” layers consist of a sheet of high-quality absorbent cotton and three layers of thick gauze. These layers are crucial for achieving the high level of absorption that meets TrainBuddies™ standards.
  
• 
  : The outermost layer is made from TPU Waterproof fabric, which protects your child’s skin and clothes from any fluid. Thermoplastic Polyurethane (TPU) is free from harmful solvents and chemicals, making it a toxin-free and environmentally friendly option that ensures your child’s safety. This layer also features a cotton cover that has fashionable prints and designs that your toddler will love, making it hypoallergenic!

Yes! All TrainBuddies™ underwear is unisex and works great for both boys and girls. The absorbent area is built where it’s needed most — and the design is neutral enough for any toddler to feel like a “big kid” in style.
