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.

Worth the $

Bought these instead of store brand once because they were on sale and now we can’t go back. My son loves how soft they are, and they fit great.

Virtually Leakproof

We've used these for a few months and I don't think there's been a leak yet! Plus, the material seems to be pretty strong/rip-resistant (important for us, since my preschooler tends to jab his feet at the openings when he puts them on!)

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.

Best Overnight Protection Available!

Excellent nighttime protection! Better than any brand I have used on my grandson. The waist has a better fit and the diaper area is more absorbing than the leading brands and you can not beat this price! I know they don’t have the logos the other brands do but my grandson don’t care and neither does the trash can! Exceptionally great quality!

My son said they were comfortable, and I was looking forward to saving a little money on overnight pull ups, but unfortunately they leaked quite often for us. We ended up washing bedding 1-3x a week because they would leak.

Thank you for trying Ninjamas and sharing what happened, Dan. We understand the importance of finding the perfect nighttime underwear for your kiddo, and size and fit are important to this process. The large is more absorbent and holds more and may provide better protection for your 5-year-old. We want to discuss this further with you. Please call us at 1-833-NINJAMA (646-5262).
