I was in the kitchen when I heard, "eeeeeeeewwwwww yucky yucky yucky!" Then, quick little footsteps.
And then, it happened. The celebratory potty fanfare.
I ran into the living room, and Lily was sitting on the potty. The potty, which she had filled with pee.
I've been letting Lily just run around naked from the waist down. It's gross, I admit. But she starts to go, and I run and set her on the potty. Usually it's too late. And more often, she just holds it until she's wearing a diaper. (when she's sleeping, or when we leave the house.)
But today, when she started to go, she put herself on the potty.
Major progress. Major.
