When Peanut was 3, he was sitting in the back seat of my car, all strapped in his seat, playing a video game. All of a sudden what should I hear come out of his mouth but, "DAMAGE!" "What did you just say?" "damage. grownups say it sometimes." Oh. I didn't know whether to laugh or tell him not to do it again. His intent was clear, he was angry enough to swear, just not sure how to do it. I asked his pediatrician about it. She said, "it is a great sign of intelligence, and reasoning skills. He needed a way to express himself, so he found it." For a couple of years it was his word of choice.
