I'll be becoming a stepmom in less than three months and we're trying to come up with a way for my fiance's kids (ages 9 & 12) to address me. They have a mom, so "Mom" isn't appropriate. "Stepmom" seems a little Cindarella-ish. And just my first name is too informal for an adult and a person deserving of a respectful title. I can't be the first person to face this. Any ideas????
