Good Quality and extremely Affordable!
Size: Size 6 (100 Count), Size: Size 6 (100 Count)
I was tired of paying $60+ for a pack of diapers and we have used Mama Bear Water Wipes for years with our kids, so decided to give these a try. Soft, super lightweight, and holds very similar capacity as the Pampers we’ve used for years. No smell, no rashes, and no rips or tears in diapers. Great quality at a low cost — I would absolutely recommend trying if you’re looking for affordable option without sacrificing quality. We’ve had a subscription for about 3 months now and really like these!

Would give them 5 stars if they were TCF
Size: Size 5 (124 Count)
These diapers fit my baby well. Many brands I’ve tried seem to be too tight in the waist/bulky on the bottom for my baby, but not these. I wish they were TCF, but as far as I can tell they are only ECF, so they’re a backup diaper for me as I try to buy TCF. The only other drawback is that the ruffles are pretty small so that’s less leakage/blowout protection but it hasn’t seemed to cause much of a problem for us. They’re pretty soft and stretchy. I like that they have a wetness indicator. Pros: Price Soft Stretchy Good fit for my delightfully chunky baby Wetness indicator Not bulky ECF* Cons: *Not TCF Small ruffles

A Catastrophic Failure in Diaper Form
Size: Size 2 (184 Count)
I’m not sure if I just got a bad batch or if these diapers are always this horrendous, but I will not spend another dime to find out—and I strongly urge you to do the same. I loved this brand’s Gentle version. They were everything you want in a diaper: super absorbent, well-fitted, no blowouts. I was their biggest fan. So, when the Gentles weren’t available, I thought, Surely the Plush will be just as good, maybe even better! I have never been more wrong. Let’s start with the tabs. These things are folded up like some kind of sick joke, requiring you to unfold them in three separate, precise movements. Miss a step? The tab rips off in your hand, leaving you holding a now-worthless scrap of disappointment. This happened to me. It happened to my mother. It will happen to you. But wait, there’s more! The side wings are a disaster. The right wing is disproportionately longer than the left, which means everything in this diaper is permanently listing to the right like a sinking ship. The left side? Practically non-existent. As a result, I have experienced more blowouts with these diapers than in my daughter’s entire life combined. I don’t know what sorcery was used to engineer a diaper that actively funnels poop toward the worst possible escape route, but here we are. And because I was foolishly optimistic, I bought a month’s supply. So now I'm locked in a psychological battle with my own stubbornness. I could throw them out, but that would be admitting defeat. So instead, I soldier on, knowing each diaper change is another step into madness. Please, learn from my mistake. You don’t have to live like this. Let me be your tribute, the sacrificial parent who suffered so you don’t have to. We’re already running on fumes as newborn parents—don’t make it worse by willingly subjecting yourself to these truly useless diapers that will rob you of your last remaining shreds of sanity. Save yourself. Run.

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.
