It is inevitable. At some point in the life of every child, they think the word "poop" is the funniest thing in the world, and will use it at every given opportunity.
Examples:
Sunday night, trying to get Julian to poo on the potty:
Me: "Come on Julian, you can do it."
Julian: "Mommy, you are a Poo-Poo head."
Tonight on the way home from daycare:
Me: "Julian, what did you have for lunch today?"
Julian: "Soup."
Me: "What kind of soup?"
Julian: "Poop soup and chicken and hamburger poop."
Of course both occasions were followed by hearty laughter (on Julian's part) over just how hilarious he is.
Then there is little Noo-Noo... sure, she takes my breath away now, just wait until she starts calling me a Poo-Poo head.
