Today, I changed my first diaper outside of the home and found a need for the wetbag, but I was wondering how often I should wash the wetbag after I dump the diaper into the diaper pail at home. I don't go out everyday, but is it silly to wash the wetbag after only one use? How often do you wash/change it for a clean one for your diaper bag? Also, how many travel wetbags do you own?
