Mo has lots of nicknames. Mo being one of them, of course. But we also call her a lot of other things. Mose, Mosey, Mosey D, MoMo, Mo Doan, Miss Mo, Mad Mo. My mom calls her Mosie (pronounced the same as Mosey, but that's her special spelling). Sometimes she's Punkin or Peanut or Peanut Pie. Sometimes Peens, which is an odd abbreviation of Peanut. I also call her Big (which came from Biggest Girl or just Biggest).
Mike and I will call her funny variations of Mo. Like Motown, Motel 6, Mozilla Firefox. Or Mozambique, Moby Dick, Motor City Madwoman. Now I can't stop. Mo Rocca, Mo Money Mo Problems, Motorola, Mochaccino, Holy Moly. And so many others.
When she was really little we called her Princess and the Pee (because she got upset so quickly after peeing her diaper!), Princess Pooper, Billy Goat (because of goat-like noise she made) and Pea Pod. None of those have really stuck though.
But one that did stick from early babyhood, and that I think is my favorite, is Peach. Or Peachy, Peachest, Peach Pie, Peachy Pie, and Peachest Pie. I think it started because she had peach fuzz hair, but also, she really is such a sweet little peach.
