Why Disposables and Diapers Fail

It's not that you're doing something wrong - it's that traditional methods weren't designed for families with full-time schedules. Disposables seem necessary because daycare needs containment, but they accidentally slow down learning because kids can't feel wetness

1. They destroy your budget: Parents spend $50-80 monthly on disposables, adding up to hundreds or thousands over extended potty training periods that drag on for years.

2. They create zero motivation: When toddlers stay completely dry and comfortable in super-absorbent diapers, they have no reason to change their behavior or use the potty.

3. They make kids dependent: The longer children rely on diapers that do all the work, the harder it becomes to break the habit and develop independent bathroom skills.

Frequently Asked Questions

Who created Cerise 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 Cerise? +

We’re not diapers. 

We’re not pull-ups. 

We’re not plastic.


Cerise 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? +

Cerise 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 Cerise 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 Cerise 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 Cerise 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 Cerise'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 from 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 Cerise 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.

Is Cerise Underwear suitable for both boys and girls? +

Yes! All Cerise 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.

Is it really Leak Proof? +

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? +
