Not every baby spits up at every feed, so exact numbers can vary. As a rule of thumb, it's a good idea to keep at least three or four clean burp cloths on hand every day. If you wash your burp cloths after each use, you might not need any more than this. However, given the fact that most new parents have precious little time to spare, planning to wash each cloth straight after use might be wishful thinking. We recommend purchasing at least 12 burp cloths, so you can rotate them daily.
