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.

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!

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.

These have worked alright for our child. I will say that if they wear it longer than 8 to 10 hours you will be having leaking if they are having to go through the night. Haven't really had any issues with tearing while being worn.

reply from Pampers Response

We're so sorry you experienced leaking at night with Pampers Ninjamas Nighttime Underwear, Sara. Size and fit are a huge part of finding the right diaper for your baby, and it's important to know that frequent nighttime leaking can be a sign that a larger size might suit your little one better for overnight use. We'd be happy to help you find the best size and fit. Please call us at (800) 726-7377 when you have a moment.

Work, but smelly

The fit on these is good for my little one with big thighs. There haven't been any leaks in the few days they've been worn. However, they smell. There's a fake lemony scent that I didn't smell before opening the package, so I can only assume it's intentionally added to the product. Nowhere on the packaging is it disclosed, and I wouldn't have bought it had I known. For that reason I won't buy them again.

reply from Ninjamas

Thanks for sharing your feedback with us, JC, and we're sorry for your disappointment with the scent of Ninjamas. Not everyone agrees on the same level of fragrance, and our research team talked with parents to deliver a scent that offers a fresher laundry-like scent and not a baby-like scent. We will share your comments about the scent, as well as wanting it to be stated on the packaging more clearly, with the team. For more help, please give us a call at (800) 726-7377.

Absorbent but Overly Scented

These are absorbent and work well but they smell STRONGLY of detergent or soap. It's a shame because otherwise they are great!
