Use and Care

Prep: The 100% certified organic cotton in Smart Bottoms diapers has been minimally processed, which means there are still some natural oils in the fabric. It is recommended you wash your diapers 4-5 times before use to help remove some of the natural oils. Diapers will reach their maximum absorbency around 8-9 washes.

Directions: Adjust the rise snaps and place the diaper under your baby. Fold the attached insert to fit your baby's needs, then pull the diaper up through the legs and fasten the waist and hip snaps. Remove diaper when wet or soiled and store dirty diapers in a dry pail. Do NOT soak.

Wash Instructions: Shake solids into the toilet before placing diaper in the wash. Rinse with cold water. Wash on hot. Do NOT use the sanitize cycle. Run an extra rinse. Dry on warm or line dry. Do not use fabric softener or diaper creams.

I love the fit and how absorbent these are. They take forever to prep though! It takes me 10-12 washes before we don't get leaks.

It takes a lot of washes to prep the diaper but once its done it is bulletproof. No leaks and super trim.

Fits great and so absorbent!

These are the first diapers I reach for in our stash. The fit is great around my daughters chunky thighs and hips, no red marks! The wide, non-encased elastic is unique and I think is the key to no red marks. They hold a LOT of liquid also. (She is currently EBF also and we've never had an EBF poo leak w/these.) I don't mind all the prepping, I love the 100% organic cotton against my baby so it's worth the time to wash those natural oils out. USA made too!
