Yes, they can be used at night, but we suggest adding extra inserts. The reason is that children often don’t wake up when they’re wet, so they may not have control during sleep. Additionally, tossing and turning during the night can sometimes cause leaks due to a loose fit.

Crafted using high-quality fabrics and a waterproof outer layer, our Markiv Potty Training Underwear offers a comfortable and effective solution for potty training toddlers.

Let’s break down the layers of UpLairy Training Underwear:

• The Inner Layer
  Made from premium, organic cotton that’s un-dyed and free from harsh chemicals, this layer is incredibly soft and safe for sensitive skin. The breathable cotton helps reduce the risk of rashes and protects against allergens like dust and pollen.
  
• The Absorbent Middle Layers
  Designed with a blend of super-absorbent cotton and three thick layers of gauze, these middle layers ensure the underwear effectively soaks up moisture just enough but still gives that wet sensation to signal your child that peeing/pooping in the underwear isn't normal, promoting potty training success-this is what "Stay Wet" technology is!
  
• The Protective Outer Layer
  The outer layer is constructed with waterproof TPU fabric, providing a reliable barrier to prevent leaks. TPU is free from harmful chemicals and environmentally friendly, making it a safe option for your child. Plus, it’s finished with playful, stylish prints that are sure to delight your little one.

Our training underwear stands out due to its smart 3-layer structure, making potty training more effective for both children and parents. Here’s how:

• First Layer [Awareness Layer]: Unlike diapers or pull-ups, our underwear doesn’t mask the sensation of being wet. With our "Stay Wet" technology, it allows your child to feel when they’re wet, making them more aware and helping to accelerate potty training while minimizing leaks.'

• Second Layer [Backup Protection]: This secondary layer acts as a safety net to contain any unexpected leaks, ensuring peace of mind for parents.
  

With Markiv Potty Training Underwear, you get the perfect blend of comfort, cute design, and reliable protection, making the potty training journey smoother for everyone involved.

Our sizes are based on your child’s weight. If you’re uncertain or your child is in between sizes, we recommend choosing the smaller size since our underwear has a stretchy, snug fit.
