DON'T SLEEP ON THESE DIAPERS! (but your baby should)
Size: Size 3 (40 Count)
I was skeptical at first trying out the plush version of this diaper because I thought the mama bear gentle touch was just OK and you can find a better diaper for the same price point. I saw these on prime day for the same price as the gentle touch and said why not. I was very, very impressed. They are soft and flexible with a satin-like exterior; similar to the feel of a hello bello diaper. The plush version definitely feels more quality than the papery gentle touch ones. I first tested the absorbency using 12 oz of water, waited ten minutes and dabbed dabbed dabbed. Seriously NO moisture! In comparison to the gentle touch diaper that had obvious moisture after the same test. I put them to use on my baby, who just for reference is 19lbs, for an overnight and the diaper did not leak and was only damp in the morning, not wet! Amazing. She is a moderate wetter but I still think that performance is great because in comparison to gentle touch, the diaper was wet on the inside after only three hours and I had to consistently use diaper cream so rash wouldn't develop; I would have never used the gentle touch as an overnight diaper. Seriously, for .21 a diaper for size three these diapers are a steal. DONT SLEEP ON THIS DEAL, PICK UP SOME MAMA BEAR PLUSH DIAPERS!

Not the Same 🤍
Size: Size 2 (184 Count)
I loved the Mama Bear size 1 diapers, so I expected the “plush” size 2s to be the same. Unfortunately, they feel completely different. These seem thinner and not quite as absorbent as the size 1 regular pack. The design is also really busy, which makes the wetness indicator harder to see at a quick glance. With babies, that little line matters more than you’d think. I’ll still finish the pack, but I’m not sure I’d repurchase this “plush” version. If you’re choosing between them, I’d recommend sticking with the regular pack instead. In comparison, Huggies still perform better than these for us. 🤍✨ They don’t hold blowouts at all but they do fit well. They’re also not stretchy. I noticed the print on my baby’s legs.

Great cost efficient option
Size: Size 4 (36 Count)
I switched over from Millie Moon and really like these. They’re affordable, don’t have harmful additives, and are soft and gentle on my babies. Holds a significant amount and doesn’t leak even on overnight wears. I like the simple non character design as well.

Every other diaper leaked
Size: Size 7 (92 Count)
I bought these diapers because they were the cheapest available to buy with a gift card my family was given. Normally I use the bulk store brands. The diapers were very hit and miss. It varies from diaper to diaper even in a pack. My son does urinate heavily but even before he would get anywhere near a “full” diaper it would leak! Leading to wet pants and messes. We’ve never had this problem with other diaper brands. Even our cloth diapers hold better than half of these did. For note he falls below the max size for these diapers by at least 5 lbs. I don’t plan on repurchasing these because of the leaking issue. Beyond that they were easy to use like any other diaper, didn’t cause diaper rash, held together, but was subpar in absorption.
