    Only the Best for Your Baby 
    We use only 100% certified organic cotton inside our diapers. Your baby’s skin will not be exposed to harmful pesticide residue or petroleum based fabrics when you use Smart Bottoms. The natural fibers will reduce, if not eliminate diaper rashes as well as promote early potty learning.
    Prepping Your Diapers
    Because we use 100% Certified Organic Cotton Fabric it will take 6-8 washes before your diapers are fully absorbent. We do not use chemicals to strip the natural oils from our fabric so it will take a few extra washes before they are ready to use, but it will be so worth it! How hard your water is, the type of detergent you use, and what type of washing machine you have will all factor in to exactly how many washes it takes to fully prep your diapers. We recommend testing a dry diaper before you use the first time by pouring a small amount of water on your diaper. If it absorbs instantly, they are ready to use! If it takes even a few seconds to absorb, wash a couple more times and try again.

Smart Bottoms does not allow shipment of their products outside the US.

The Smart bottoms 3.1 Organic cotton AIO diapers take a very long time to prep wash and the fit was never quite right along the belly. The material is soft but not quite absorbent enough and only would last my heavy wetters an hour or so even after all the prep washings. Always had to add a booster. Wanted to love as they have the cutest prints but just not a fav here unfortunately!

I love Smart Bottoms! The 3.1 is my favorite. I love the colors and prints and how they fit so trim on my little. It feels good having a natural fabric against her skin.

I love smart bottoms they fit my lil one so well. Only thing I don't like about it , is the prep time but I bought more so must not be that bad :) I recommend this diaper and this shop to everyone.
