On my last visit with my nephew, I asked him to gimme some sugar. He's almost 5, and he already knows what that means. I suspect he normally hears it from his Gigi who says something along the lines of "Gimme some sugar, my doodlebug." And then she hands him money or peanut butter crackers. He has been trained properly. I don't think I will continue with the whole sugar, baby, sweetie thing. Only certain people can pull that off, and I am definitely not one of them. I do call one of the cats sweetie, but they seldom roll their eyes at me so I feel safe in doing so.
