Well, it happened. My 2-year-old said "fuck" to me. He didn't want his diaper changed and yelled it out while i wrestled him onto the changing table. I immediately started talking about ducks and got him quacking along with me but was thinking, really? Your grandparents are coming to visit tomorrow. Don't be starting this now! I've tried so hard not to swear when he can hear me. I think that he also called the cat the "fucking cat" about a half hour later, but he wasn't speaking quite so clearly and wouldn't repeat himself, so I can't be sure.
