#1 and #2

In an effort to entice Parker into telling us when he needs to go pee and poo, we told him that pee is sometimes called #1 and poo is called #2. It took him about 2 seconds to grasp that concept and immediately started calling them by numbers. Then he said, "#0 is a fart." Which I thought was pretty perceptive and so now we call a fart 0.

He still isn't telling us when he needs to go, though.
