I got out of the shower this morning and instead of grabbing my usual lilac towel, I got a dark purple one -- because the lilac ones were in the washing machine. My daughter looked up and said, "Where pink towel, Mommy?" I told her it was dirty so I was using a purple towel. She got an evil grin on her face and said, "Mommy have poo-poo towel! Mommy have poo-poo, pee-pee towel." And then she burst into gales of laughter. Potty humor starts early.
