BEST overnight protection for toddlers! No leaks!

KelsNovember 15, 2025

I’ve tried several brands of nighttime underwear, and Ninjamas have become our clear favorite for my older toddler who isn’t fully potty trained at night yet. These truly stand out in every way. Leak Protection: The biggest win for us is that they never leak. We’ve gone through many overnight products that claimed to be extra absorbent, but these are the only ones that consistently make it through the entire night, even on nights with heavier wetting. No more soaked pajamas or changing sheets at 2 4 am - such a relief! Fit & Comfort: The fit is fantastic. The waistband is honestly one of the best features. It’s soft, stretchy, and really flexible, so it moves with my child without digging in or leaving marks. The leg openings also have a snug but gentle fit that helps prevent leaks without feeling tight. My toddler stays comfortable all night and never complains about them. They’re thin and discreet under pajamas, and they look more like real underwear than a diaper. The fun designs are a bonus too! Performance: They hold up great through long nights, travel, and even nights where my toddler drinks a ton of water before bed. The absorbency and fit have been consistently reliable for us. If you have an older toddler who needs nighttime protection, I can’t recommend Ninjamas enough. They fit well, feel comfortable, and most importantly keep the bed dry every single night. Absolutely worth it! Read more

Great fitting for big kids and NO LEAKAGE!

AngOctober 18, 2025

Works great fornthe added night time protection. My son has accidents at night due to the meds for his seizures he sleeps so hard he dosnt wake up and these ninjamas have been a real lifesaver. Saves me from washing bedding daily and saves from having tonreplace stained stinky mattresses all the time as well. They dont leak like a lot of the other brands out there do and they fit well. They are not to tight so its comfortable and alsonthey have a look of real underwear more so then other brands. My son can go to bed with ease not having to worry and panic about having accidents. Definitely a game changer for parents everywhere with older kiddos having night time accidents. You will not be disappointed Read more

Best night time diaper

MarciAugust 7, 2025

We have been using these for night time for our special needs 9-year-old. He is 56.5 lb and 4 ft tall. We use size large. They're perfect! We have had one minor leak and that was because he had a restless night and moved around a lot. Other than that these things are amazing! Read more

Great for older kids

BethSeptember 23, 2025

These are great! My 6 year old still struggles with bed wetting but these make the embarrassment a little better. He loves ninjas so that’s a plus. They hold urine with no leaks and you can give confidence back to your little one by using ninja Jammies. No skin irritation is noted. My child is average for a 6 year old and weighs 50 lbs he’s a S/M Read more

Best night time underwear/diapers

Diana OrtegaJanuary 3, 2026

These nighttime underwear/ nighttime diapers are amazing. They help avoid bed wetting like 95% of the time. And for out little guy that is amazing because when we first started training for night time potty breaks and sleeping through the night Huggies would like like 30-35% of the time and all other we tried would leak over 60% of the time so finding these was awesome. He also was able to pull them up and take off easily which helped him want to go to the bathroom when he did need to go. Or if he felt it too late he was able to change himself and go back to bed. Where others he would cry and give up. Read more

Love these - make larger sizes!!

MICHELLE BENNETTDecember 24, 2025

These are the best pull ups especially for kids with booties. My grandson is severely autistic and other genetic disorders. These don't leak, they cover his entire bottom. PLEASE MAKE LARGER SIZES!!! My grandson has outgrown the large and we are struggling to find a replacement. Read more

More Comfortable than Pullups

AmandaGSJanuary 6, 2026

After using Pampers diapers for our son from birth to potty training at 2.5, we naturally transitioned to Pampers Pullups for sleeping. They worked well, but he started complaining about them itching on the sides. They were clearly uncomfortable. When we started using these, he weighed about 32pounds, and I was worried they would be too big. They work just fine. While he rarely goes at night, these are a fantastic backup. They're soft and comfy. Read more
