Parker made up a sign and sound effects for when he has a dirty diaper. Lately, he uses this sign every time we change him. One day, I told him "There's no 'yuckies,' just pee-pee." He laughed hysterically, and that has been his new word he likes to use. Craig was home alone with him a couple of days ago, and they were going through all of the words and people's names he knows (including pee-pee!), and halfway through, he fortunately thought to grab the camera. This is our little boy laughing about his new potty talk.
