What does it take to be a big sister?

If you were to ask Daniella this question, she would probably ask: "one just needs to have a younger sister!" Well, from the time Daniella first saw Sophie at the hospital, she demanded that we give the baby to her. She is the first one to run up to the crib when Sophie starts crying, wants to hold her, and even tries to tell us what to do. There is one little problem, big sister tends to overestimate her own abilities. She thinks she is even big enough to be mother :-).
