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.
