There’s no hard and fast rule on this one, and the answer depends on the age of your baby, and what you use the washcloths for.The number of washcloths you will need for your baby will change as they get older. A newborn needs about two to four washcloths per day, which can be used for bath time, clean their face and hands, diaper change, wipe off milk dribbles etc. Once they get older, you typically need one to two washcloths per day, usually to use as face towels, dry off sweat or to wipe their hands.
