Work 👍 great
Size: Size 1, Unit Count: 128
Diapers work 👌 perfect. I received them a day late & needed them for a baby shower. Amazon Prime stated that I would receive them the next day, Diapers arrived in 2 days. Therefore i went empty handed to the baby shower. Be warned Amazon Prime does NOT always deliver as stated.

Softest diaper ever.
Size: Size 1, Unit Count: 44
I’ve tried almost every brand on the market. I finally settled on these, and they are worth every penny.
Here’s why they stand out:
Absorbency: These are incredible for overnight. No leaks no late night changes
Material & Feel: They are incredibly soft—almost like cloth. If your baby has sensitive skin or is prone to redness, the breathable material makes a huge difference.
Fit: The leg cuffs are stretchy but secure. They dont leave that deep red marks that cheaper diapers do.
Wetness Indicator: The line is clear and easy to see, even through a onesie.
I bought a size 1 for my 9lb baby and it fits perfectly.

Best diaper
Size: Size 5, Unit Count: 84
The only diaper band we ever buy. We’ve never had any blowouts because of it. It’s easy to use and hold up a lot. It’s really soft and doesn’t give any rashes. The material is great. Doesn’t really stop odor not that I expected it.
