Someone asked a question about who goes "tinkle" sitting down. Got me thinking about little-kid words for things. When I was little I used my "tinkler" to go "tinkle" in the potty ("pee" and "poop" were too indelicate for her). Sometimes I had to go "grunt," too. Someone else posted something about their "underpants," a word I like almost as much as calling it my "underwears." I knew someone whose child wore "potty pants" (cotton training pants) while potty training.
What other silly words do people remember or use in their play?
