I'm not sure who created this picture but it made me chuckle. Levi's Dr who has several children said something along the same line about pacifiers. Levi's had fallen on the floor during a visit and the Dr said for the first child when the pacifier falls on the floor the parents take it home and disinfect it. For the second child you pick it up and wipe it off before giving it back to the child. For the third child you just pick it up and put it back in the babies mouth!
