reply from Ninjamas

We know how frustrating leaks are, Kaylynn, so we're very sorry for this experience with Ninjamas. We're here to help and would like to share that size and fit are a huge part of finding the right diaper for your baby, and as you know, babies come in all different shapes and sizes, so diapers fit every baby differently. Our diaper sizes are organized by weight, and since no two babies are the same shape, you will notice some overlap between sizes. In most cases, your baby should be within the weight range for the size you are using, but if leaking is occurring, it may be an indicator to go up a size. So we can help get you and your baby back to leak-free days and nights, please give us a call at (800) 726-7377.

reply from Pampers Response

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).

Leak proof for dry skin

[This review was collected as part of a promotion.] To be honest, I was a bit skeptical when I recieved these. When I saw that they were scented, I had my doubts. It wasn't until we actually opened them, that noticed that the scent was barely these. These are nice and thin, so they fit nicely under my son's jammies. My son says that they are very comfortable. We have used these for a few days now, and no leaks.

Ninjamas

[This review was collected as part of a promotion.] My child was happy with the fit of the Ninjamas. They were comfortable and felt more like panties than a diaper. They were more absorbent than a pull up, but not as much as a diaper. I do not recommend if your child is a heavy bed wetter.

great night time underwear

[This review was collected as part of a promotion.] My daytime potty trained toddler usually soaks her sheets with other brand diapers. I usually have to use 2 together and they still soak through. I am so glad I tried these it has save me from doing laundry as well as my Lo does not wake up crying since she is not soaked. usually the other underwear/ pull ups get full cause some redness marks due to their design. not these these are stretchy and look very comfortable.

So I received Ninjamas free from Influenster and tried them for two night in a row, and I can say they did not disappoint! They hold so much More urine than any other night underwear Ive tried for my two boys! I would definitely recommend! My boys also said they are soft and feel better than other brands weve tried. The sides are so soft and the front and back cover more. I am very pleased with Ninjamas!
