Very good, very cute newborn diaper
Reviewed by: (Verified Buyer)  from PA. on 1/5/2018
I had one of these for my newborn. The fit was good, very trim. It was one of the first to be grown out of, but still got a couple months' use and was worth it. Love the mountain bike print!

Good fit, not very absorbent
Reviewed by: (Verified Buyer)  from Huntington. on 10/9/2017
I loved the Thirsties prints and that these snap down for the umbilical cord, plus they are soft against his skin. At 6 weeks and almost 12 pounds he still has room to grow in them. We haven't had any major blowouts, as the leg holes fit well two days after birth, and fit even better now that his thighs have gotten chunky. So I like the fit, and the sewn in soaker fits in the diaper perfectly without having to fold anything, making it perfect for husband to just throw on him without having to think about it. But from about 2 weeks he was soaking through them within a few hours, and now is down to less than an hour... I only use these at home as a daytime diaper, when I don't mind changing his clothes or mine as much. He leaks though the sides when he is laying on his side, and through the front when he is on his back. I suspect that this is because the soaker is attached in the front and is therefore not very thick there... I've attempted to fold it for more padding up front to no avail. They might not leak as much for girls or babies who wet more towards the middle. Cute, glad I had them for his cord stump, easy to use, but short-lived.

Not very absorbant
Reviewed by:  from Wyoming. on 8/10/2017
These had a great fit on my 9-10 pound baby and had a lot of room for her to grow, but they leaked every. Single. Time. And bad. You'd think with that big, thick attached insert it would be super absorbant but it's quite the opposite. It was from Amazon, but I'm returning it. Shame :(

More use than expected
Reviewed by: (Verified Buyer)  from Newton, MA. on 2/6/2017
I bought a few of these, thinking I might get 1-3 months use out of them before needing to switch to the regular AIOs. My daughter recently turned 3 months and these still fit! I'm thinking I might get another month's use out of them but it is nice to see that even though they're newborn sized, they fit longer than expected. And I love the prints offered.
