Description Kristy, Mary Anne, Claudia, and Stacey are best friends and founding members of The Baby-Sitters Club. Whatever comes up-cranky toddlers, huge dogs, scary neighbors, prank calls-you can count on them to save the day. Baby-sitting isn't always easy, and neither is dealing with strict parents, new families, fashion emergencies, and mysterious secrets. But no matter what, the BSC have what they need most: friendship.
