Early on, we made a conscious decision to change some words in our house. We always make sure to say our kids have "strong legs" that help them cartwheel, run, and kick. And we are especially careful about saying the "F" word- fat. That is a banned word in our house. I used to say it a lot, but as soon as we heard the kids say it, we realized that the word fat needed to be exiled from our home. It's not that I don't want them to know the word, but rather I don't want them to associate themselves with the word.
