Once baby arrives, parents get potty mouth. Words like "poop", "pee" and "spit up" fuel entire conversations. Though just about every mom and dad freely discusses the bodily fluids of their babe, would you go as far as to decorate with the terms? Plain Mary offers a Gross Burp Set ($40) of cloths embroidered with the words "poop", "tinkle", "gross" and "puke". Would you buy them?
