Allie's naughty words and daughters

Allie has had a "naughty word" obsession lately, which is both good and bad. In November, when we got Charlie and the Chocolate Factory, she copied Mike Teavee's statement of "it's stupid." We didn't want her to say that, so we suddenly had to become very careful about our word choices. We had to say "silly" instead of "stupid", and when somebody forgot, we had to correct him or her. One time someone said stupid and she corrected with silly! She and my mom's friend have mutual admiration, so Allie is frequently with her, but unfortunately she and her family often have colorful language. When my mom's friend (Jackie) swore, Allie copied her, and Jackie felt terrible. Allie learned another, even worse (and I mean really bad) word from Jackie's family and parroted the two words in our house. Luckily, after standing her in the corner, she no longer says these words. She now likes to say "dang it"--mostly just because it's a naughty word. At least it's better than what she said before.
She now is the naughty word sheriff. When she hears a naughty word, she recognizes it and reacts. When her mom was on the phone and said a word that wasn't as nice as it could be, she said to me (with her scolding voice and face), "You hear what mommy say? Crat?" That's not a misspelling; that's how she said it. Almost every day she asks me to watch Charlie Brown with her. When Charlie Brown says something like "You must think I'm stupid," she says something like "We don't say that word." She even reacts to perfectly normal words like "odd" or "rude". "Don't say that! That's a naughty word!" Not that we said anything really bad before, but it has made us watch our words.
We've also been teaching her about family relations, that she is a daughter, and now she keeps insisting, "I have daughters." When we tell her that she doesn't she says, "I have mothers." When we explain in detail how she is a daughter and a granddaughter, and has a mother and a grandmother, she keeps returning to "I have daughters." The other day she even said, "I have sixteen daughters!" I guess that means once again there are five generations in our family.
