Claudia and Mean Janine (The Baby-Sitters Club #7) by Ann M. Martin

Claudia's sister, Janine, is too busy being smart to be nice to anyone-even their grandmother, Mimi. But Claudia doesn't have to see Janine too much this summer, since the Baby-sitters Club is starting a new play group. It's going to be so much fun!
   But then Mimi has a stroke, and the whole summer changes. Now Claudia is "Mimi-sitting," and Janine is no help at all. How can the Kishi sisters get along when Janine is always so mean?
