New bad words

So sweet, so innocent. Ahhhh the trouble free life of a 1 1/2 year old boy. My son runs around screaming phrases "aww dam" and " aww god". It is fun to hear him say bad words that he cannot quite pronounce yet, like the word shit, he says it more like "cheet" and bitch sounds more like "bets". Yeah, yeah I know its bad to teach these things to a kid, but hey he's in his mocking stage and it's going to happen. You cannot shield a kid from these things. I herd George Carlin say "kids don't learn that these words are bad until one day they say one and WHAM a smack in the head, when he says another out of the reaction to the pain WHAM" thats a tough way to learn. He just learned how to make the sound effect of a gun when he wants to shoot it, I can't wait to smack him when I hear "die bets die". AHHHH, the punishing I get to look forward to giving. (thats supposed to be funny, I don't plan to beat my kid people).
