"When Kristy Thomas has the great idea to form a baby-sitters club--a chance to earn money and spend time with her friends, all while doing something they each love to do--she has no idea how much the club will change everything. Crank calls, uncontrollable toddlers, wild pets, untruthful clients...running a business is hard work! Kristy and her co-founders, Mary Anne, Claudia, and Stacey, are sure they can handle anything. But only if they stick...

Joining the Baby-sitter's Club after moving to a new town, Stacey helps her new friends outmaneuver a rival sitter group while coming to terms with her diabetes.

Dawn, the newest member of the Baby-sitters Club, gets more than she bargained for when her first job turns into a disaster and she has problems with Kristy.

"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?" --Back cover....

During the summer before their seventh-grade year, Kristy, Mary Anne, Claudia, and Stacey tackle difficulties, including family problems, crushes, moving, and making new friends.
