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

I didn’t have high expectations for these. My son is 4, autistic, non-verbal and not yet potty trained. He drinks a lot of water throughout the night, so I didn’t think these would hold the amount he pees without leaking. However, they actually have held up. I was changing bedding and washing bedding EVERY Single Day!!

finally, some reliable leak protection!!!! We were fans of goodnites, but they stopped fitting well as my kids got older. Heard good things about Ninjamas, gave them a try, and not looking back.

Useful when child is sick!

Very useful if child is sick! I bought size S/M for a 40 pound 2.5 year old. They fit well. They fit higher up on the tummy than expected but that's not a problem. I have yet to discover a leak! They work well if child has diarrhea from the flu etc! They did not leak, whereas parents choice pull ups did. They don't look like underwear in person. My only complaint is the strong scent.
