Baby Forklift?

Sometimes Sean will randomly refer to me as "Mommy Forklift" or "Mommy Porcupine" just to name a few. Naturally I always reply, "Yes, Baby Forklift?" or "Yes, Baby Porcupine?" For example, out of nowhere he'll say, "Mommy Froggy, could you get me some milk?" I find that if he is in a "Baby Froggy" (or whatever) mood, I don't get much cooperation from him unless I refer to him as such. He keeps life interesting for us.
