SO DISSAPOINTED!
Size: Size 4 (104 Count), Color: Donut Grow Up + Cactus Cuties
I am a huge fan of honest diapers and products but i am very DISAPPOINTED in this companies policies. I got a bad batch of diapers, the tabs pulled off of more than 70% of the 104 diapers! I tried to do the right thing and contact the selling company, they sent me to to the manufacturer who eventually sent me back to amazon for a refund. However, since it took so long for me to get email responses from the providing compan and the manufacturer they only gave me a $9 refund from a $45 dollar purchase, which is absolutely garbage! I did everything they asked me to and got SCREWED because of it. I thought this company cared about its customers but they obviously dont. I have been buying honeat diapers for nearly 3 years now, but that changes today, i hope saving $30 was worth giving up a customer who bought diapers for 2 kids for 3 years! What a shame, I wish companies cared more about their customers than they do their bottom line, but that is clearly not the case. Well, with 2 more kids they lost out on at least $5k, I sure hope saving $30 was worth it to them.... What a shame..

Amazing!
Size: Size 3 (120 Count), Color: Space Travel + It's a Pawty
I cannot recommend Honest Diapers enough! After trying several brands, these truly stand out for their comfort, reliability, and eco-conscious design. The fit is snug yet gentle, preventing leaks without leaving red marks on my baby’s skin. What I love most is how soft and breathable they feel—my little one stays dry and comfortable all day and night. The absorbency is outstanding; even after long stretches, there’s no sagging or irritation. I also appreciate the clean ingredients and the fact that they’re free from harsh chemicals, which gives me peace of mind. Plus, the adorable prints are a sweet bonus that makes diaper changes a little more fun. Overall, Honest Diapers deliver exactly what they promise: premium quality, safety, and comfort. They’ve made diapering stress-free for us, and I feel confident knowing I’m making a better choice for both my baby!

Soft and no more break out rashes
Size: Size 5 (84 Count), Color: Wingin' It + Catching Rainbows
Love these diapers! My fourth baby would keep breaking out and no matter what creams we tried it would not get better until we made the switch and it was instant relief and no more bumps. Baby was a lot happier as well! Give them a try you won’t regret it.

They fit small and waistband doesn’t secure
Size: Size 4 (104 Count), Color: Wild Thang + All the Alpacas
I love the prints and I love that they are unscented. We haven’t had any issues with irritation. I have used the wipes from this brand too, and they are awesome. However, these diapers fit pretty small (inaccurate from the weight chart) and are pretty short. They don’t work for long, chunky babies. I wish they would fix the waist band because there needs to be an extra place for the sides to secure onto. The diaper moves really easy (especially the waist band in the front) and we have had several leaks and blowouts. I also think there should be a blowout barrier in the back. I love the idea, I just think there needs to be some small tweaks to make these worth the price because they are pretty expensive.

Best diaper for my family
Size: Size 3 (120 Count), Color: Space Travel + It's a Pawty
I really like theses for my son, they are easy to put on, they hold through the entire night of him peeing(8pm-6am) they are really soft and good quality. The only complaint I have is that my son is able to take off the tabs and he pees through his clothes but I think that’s more of a him issue. But really good value and they are clean and perfect for kinda crunchy moms as i decided on this brand when reading the ingredients in pampers, Huggies, ect. these work the best for my family . Plus they have really cute prints
