Allergens & Warnings Keep away from any source of flame. Ninjamas nighttime underwear, like almost any article of clothing, will burn if exposed to flame. To avoid risk of choking on plastic, padding, or other materials, do not allow your child to tear the pant, or handle any loose pieces of the pant. Discard any torn or unsealed pant, or any loose pieces of the pant. To avoid suffocation, keep all plastic bags away from babies and children. If you notice gel-like material on your child's skin, don't be alarmed. This comes from the nighttime underwear padding and can be easily removed by wiping your child's skin with a soft, dry cloth

Fit well, design is cute and holds alot.

My girl is a little big for her age and still uses a "pull up" at night. We've tried so many other brands and none fit or hold as well as these. While the design isn't character related, she still loves the unicorns and flowers. She is about 50lbs and wears a girls size 6 in clothes and 8 in panties. The Small/Medium fit perfectly. They don't leave lines from being too tight and hold liquid very well. The Ninjamas are also soft and comfy. She has some sensory issues and these do not bother her at all.

These are the best overnight pants out of the ones I've tried! They absorb a lot and are soft and stretchy. They are a bit pricier than store brands but the quality is unmatched,

Cute and work well but make sure you get the right size. My daughter has skinny legs and they tend to leak.

reply from Ninjamas

We're sorry to hear that you experienced leaks, Stephanie. We know how frustrating that can be and assure you that we're here to help prevent that from happening again. Size and fit are a huge part of finding the right diaper for your baby, and it sounds like they may have outgrown the current diaper size. If your little one is near the upper end of the weight range for the diaper size you’re using, trying the next size up can help, as larger sizes contain more absorbent material. So that we can best help, as well as share your experience with our Quality Team, please get in touch with us at 1-833-646-5262.
