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...

Stacey, a member of the Baby-sitters Club, learns to cope with her diabetes and her overprotective parents.

"As the newest member of the BSC, Dawn is eager to prove herself. So when a big job comes along, she jumps at the chance to show everyone what she's made of. The Barretts are even more challenging than Dawn expected. The house is a mess. Mrs. Barrett is unreliable, and the kids are out of control. Dawn knows she's a great baby-sitter, but this is impossible! She only knows one thing for sure--a member of the BSC never gives up!"--Page 4 of cover.

Claudia's participation in the Baby-sitters Club is curtailed when Grandmother Mimi suffers a stroke and Claudia finds herself "Mimi-sitting" and fighting more frequently with her sister.

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.
