Before first use the shells, stay dry inserts, and overnight inserts only need to be washed one time. Hemp/Organic Cotton inserts need to be washed 4-6 times to reach full absorbency. Please note that hemp inserts will shrink slightly during first washings making them consistent with the other insert sizing.
We recommend washing every 2-3 days. We have found that the Best Bottom system washes beautifully as it takes up less space in your washing machine allowing more room for agitation getting your diapers super clean.
