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

Ultimate overnight superhero

[This review was collected as part of a promotion.] What I like about the ninjamas nighttime training underwear is the flexible fit. I no longer have to get my toddler to do the wiggle dance to put them on, they just slide right up. She loves the design, and the name also. They are leak proof and odor free too with no poofy bottom.

Very soft for gentle baby skin!

[This review was collected as part of a promotion.] I have been using these diapers for over a month and can give my word that these don't leak at all! They are soft for gentle baby skin. And because they soak really well, there are no rashes as well. Also, I really like that these do not sag too. Definitely a brand you should consider for nighttime underwears! I received this product for free from Topbox Marketing for testing and review purposes.
