What's in a Name?

DS might be having an identity crisis, or just the opposite. Oftentimes I refer to him by names that are not his own, i.e. "tiger boy" (when he wears his tiger jammies), "grumpy boy" (self-explanatory), and the like. Or ask him if he's my "cuddle bug" or "stinky face" (from the great book I Love You, Stinky Face). He inevitably corrects me, "No, I'm [DS]." Very cute, very literal.
