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 neighbours, 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.
