What Size Should I Get?

Just go by weight! Our sizing is based on real toddler bodies — not guesswork. 

 

Our sizes typically run:
- Small: 1-2 years (7-20 lbs | 3-9 kg)
- Medium: 2-3 years (22-35 lbs | 10-16kg)
- Large: 3-4 years (35-55 lbs | 17-25kg)

 

If you're in between sizes, we recommend sizing up for more comfort.

 

💡 Bonus: Every order is covered by our 75-day fit guarantee. If it’s not right, we’ll exchange it for free — easy.

Is this better than pull-ups?

Yes — and here’s why. 

 

Pull-ups feel like diapers… so kids treat them like diapers. That’s the problem. They don’t feel when they’re wet — which delays learning.


UpAiry is different. It looks and feels like real underwear, but has just enough built-in absorbency to catch small accidents without making your toddler lazy. That sensory feedback helps them connect “I need to pee” with “I should go potty.”


It’s the difference between managing messes and actually making progress.

Can I use them overnight?

Yes! Our training pants are designed to keep your child dry and comfortable all night. They still let your child feel when they’re wet, helping with potty training even during sleep.

 

We recommend getting some extra absorbent inserts or Waterproof Mat for nighttime training for extra leak protection.

Can it handle poop accidents?

Yep — they’re designed to handle that too. Solid poop? Just shake it into the toilet and toss the undies in the wash. 

 

For messier moments, a quick rinse first helps. Either way, you’re covered.

 

💩 Handles the full potty journey
🚽 Easy to clean
🧽 Toddler-proof

 

For best results, make sure you've chosen the right size - our underwear should fit snugly around your child's legs without being too tight.

Gummies FAQ

Ingredients + Allergens

Each bottle contains 60 Gummies. Each Serving is 2 Gummies a day.

 

We keep it simple with just 3 research-backed ingredients:

  • Kiwifruit Powder (250mg) — A natural prebiotic that feeds good gut bacteria and helps soften stools
  • Bacillus Coagulans (10mg) — A probiotic that balances gut flora for regular digestion
  • Heat-Treated L. Paracasei (20mg) — A postbiotic that supports the mind-gut connection

Plus natural sweet kiwi flavor. That's it! No artificial colors, high-fructose corn syrup, GMOs, or preservatives.

 

Our gummies are free from:
ㄨ Gluten
ㄨ Dairy
ㄨ Soy
ㄨ Eggs
ㄨTree Nuts
ㄨ Peanuts
ㄨWheat
ㄨ Artificial colors & flavors
ㄨ High-fructose corn syrup
ㄨ GMOs
ㄨ Preservatives

Are they safe for long-term use?

Yes! Our gummies are specifically designed for daily, long-term use. 

 

Unlike laxatives that create dependency, our prebiotics, probiotics, and postbiotics work with your child's body to support natural gut function. 

 

They're pediatrician-recommended, third-party tested, and free from harsh chemicals — so you can feel confident using them as long as your child needs support.

Who should take these gummies?

Our label suggests ages 4+ strictly due to the standard choking hazards associated with gummy textures, not the ingredients themselves.

 

Because our formula is made from natural Gold Kiwi fruit and probiotics, many parents of younger toddlers choose to use UpAiry by cutting the gummies into small, safe pieces.

 

We recommend always supervising your little one while chewing and consulting your pediatrician if you have specific concerns

 

 

 Our gummies aid toddlers who struggle with:

  • Hard, painful poops or constipation
  • Bathroom withholding or potty anxiety
  • Irregular or unpredictable bowel movements
  • Potty training challenges related to pooping

 

Our experts carefully formulated this 3-in-1 blend to support comfortable digestion and the mind-gut connection that helps kids feel when it's time to go.

Are they backed by research?

Yes! Each ingredient in our formula is supported by clinical studies:

  • Kiwifruit powder has been shown to increase bowel movements and improve stool consistency in clinical trials
  • Bacillus coagulans has been studied for digestive comfort and regularity in both adults and children
  • Heat-treated L. paracasei has research supporting its role in gut-brain communication

While individual ingredients are clinically studied, always consult your pediatrician for personalized advice.

The Science

What's Inside 
(And Why It Matters)

Our combination of prebiotics, probiotics, and postbiotics helps support balanced gut bacteria and strengthen the signals between the gut and brain — making it easier for your child to recognize when it's time to go.

  • Probiotics

  • Prebiotics

  • Postbiotics

Ingredient: Bacillus Coagulans

Probiotics are the beneficial "good bacteria" that live in your child's gut. When they're thriving (thanks to prebiotics), they support healthy digestion and regular pooping.

How This Helps:
🦠 Restores gut bacteria balance
⚖️ Supports predictable, comfortable bowel movements
💪 Reduces tummy discomfort and irregularity

Ingredient: Kiwifruit Powder
Prebiotics act as "food" for beneficial gut bacteria — helping them multiply and produce substances that naturally soften stools.

How This Helps:
🌱 Nourishes the good bacteria (probiotics) your child needs.

💧 Softens stools for easier, more comfortable poops
🔄 Supports regular bowel movements

Ingredient: Heat-Treated L. Paracasei

Postbiotics strengthens the signals between your child's gut and brain — so their body tells them when it's time to go.

How This Helps:
🧠 Helps kids recognize when they need to poop
🔗 Supports the mind-gut connection
⚡ Works immediately (no need to survive digestion)

Frequently Asked Questions

Who created UpAiry and why?
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.

What Exactly Is UpAiry?
We’re not diapers. 

We’re not pull-ups. 

We’re not plastic.


UpAiry 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.

How do I Wash Them?
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!

Is it suitable for night time potty training?
UpAiry 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 UpAiry 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.

Our technology
Made from premium fabrics and a waterproof outer layer, our UpAiry Training Underwear ensure 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 UpAiry Training Underwear:

 

The Inner Layer

The inner layer is 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.

 

The Middle Layers

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 UpAiry’s standards.

 

The Outer Layer

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! 

How are these different than disposables?
Our potty training underwear stands out with its innovative 2-layer design, ensuring a unique experience for both parent and child. Here's the breakdown:

 

First Layer: Unlike diapers or pull-ups, this layer doesn't absorb wetness. Instead, it allows your child to feel the discomfort, aiding in their awareness. Plus, it prevents leaks, so you won't have to deal with puddles or soiled sheets.

 

Second Layer: Acting as a safety net, this layer helps reduce that any potential leaks, providing extra peace of mind.
 

With our UpAiry Underwear, you get the best of both worlds: a comfortable, cute design for your child and a stress-free potty training experience for the whole family.

I'm not sure what size to order?
Our sizes are based on weight. If you are unsure or are in-between weights, its best to size down due to the Underwear being stretchy!

 

You can find the full size guide below:

Is UpAiry Underwear suitable for both boys and girls?
Yes! All UpAiry 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.

Are They Really Leakproof?
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.
How does the 75 day risk free trial work?
