All parents remember how annoying it can be when a baby drops their pacifier on the floor. Whenever it happens, parents face a choice. First time parents typically opt for the hazmat suit route, carrying the pacifier to the kitchen and sanitizing it in boiling water. By the time your fourth kid comes around, you pick it up, you may or may not suck on it, and then give it back to your son or daughter. Not that I speak from experience or anything.
