Claudia has always been the most outrageous girl in her class...until Ashley Wyeth comes along. Ashley's really different - she dresses in hippie clothes, wears six earrings and work boots, and is the most fantastic artist Claudia has ever met. Ashley says Claudia has artistic talent, too, but thinks Claudia should spend more time on her "calling" and stop wasting time on the Baby-Sitters Club. The baby-sitters are sick of Ashley Wyeth, and they feel like Claudia is a traitor. Claudia has to decide: either the BSC or the new girl - one of them's got to go!

Claudia's not worried when she hears her newest baby-sitting charge, Betsy, is a great practical joker. After all, how much harm can one girl do? As it turns out - plenty! Claudia breaks her leg because of one of Betsy's mean jokes...and now she's talking about quitting the club. Baby-sitting might be too dangerous. The rest of the BSC decides that Betsy needs to be taught a lesson - and the joke war is on!

Stacey's parents are getting a divorce. Stacey is sad and angry, and she has a big decision to make - stay in New York with her father, or move back to Stoneybrook with her mother.

After Kristy's mom got married, her family moved to Watson's house in a new neighborhood. But the kids there aren't very friendly - in fact, they're total snobs! They criticize Kristy's clothes, make fun of the Baby-Sitters Club...and worst of all, they laugh at Louie, Kristy's pet collie, who's going blind. Nobody does that and gets away with it! Kristy's fighting mad, and she's not going to put up with a Snob Attack any longer - and neither is the BSC!

Lately, it seems like each of the baby-sitters besides Dawn has been singled out...and she's a little jealous. But now it's Dawn's turn to shine: Mrs. Pike has asked her to help prepare Margo and Claire for the Little Miss Stoneybrook contest! Dawn's going to do everything she can to help her charges win, even if Margo's only talent is peeling a banana with her feet. But then Kristy, Mary Anne, and Claudia are helping Karen, Myriah, and Charlotte enter the contest, too. It's hard to tell whether the competition is fiercer at the pageant - or in the BSC!

Stacey's so excited! She's invited her friends in the Baby-Sitters Club to New York City for a long weekend. It's going to be perfect - a party and a sleepover on Friday, a big baby-sitting job on Saturday, and lot of sightseeing on Sunday. But what a mistake! The BSC is way out of place in the big city. Mary Anne sounds like a walking guide book, Dawn is afraid of everything, Kristy can't keep her mouth shut, and Claudia is jealous of Stacey's friends. Can Stacey be in the BSC anymore?

Dawn has always thought there was a secret passage hidden in her house. But that doesn't explain why creepy things happen when Dawn's at home, or the spooky noises coming from behind her bedroom wall. Dawn is sure there's a ghost in her house! And so are the other Baby-Sitters Club members. But they're so busy with their jobs that they don't have time for a ghost hunt. Will Dawn and her friends solve the mystery...or will Dawn have to share her house with a ghost?

Mary Anne used to have to wear her hair in braids, keep her room painted pink, and ask her dad before she did anything. But not anymore. Mary Anne's been growing up...and the Baby-Sitters Club members aren't the only ones who have noticed. Logan Bruno likes Mary Anne! He has a dreamy southern accent, he's awfully cute - and he wants to join the Baby-Sitters Club. The baby-sitters aren't sure Logan will make a good club member. And Mary Anne thinks she's too shy for Logan. Life in the BSC has never been this complicated - or this fun!

Mallory Pike has always wanted to be a member of the Baby-Sitters Club - they're so much fun to be around, and she's practically a baby-sitter already. Now the club members have invited Mallory to a meeting. This might be her big chance! But the BSC isn't making it easy - they make Mal feel like a baby on a job, and make her take an impossible written test. Mallory's beginning to think she doesn't want to be a part of the BSC...or maybe she and her new friend Jessi should start a club of their own. It's time to show those baby-sitters what a couple of new girls can do!

Kristy, Claudia, Mary Anne, and Stacey try to be prepared for anything when they baby-sit. So when they hear about the Phantom Caller, a jewel thief who's been breaking into nearby homes, they come up with a plan to keep their kids safe. But when Claudia and the other girls start receiving creepy phone calls while they're out on jobs, they start to get really spooked. Will the mystery caller scare off the BSC?  

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?

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! 

Stacey and Mary Anne are baby-sitting for the Pike family for two weeks at the New Jersey shore. Things are great in Sea City: There's a gorgeous house right on the beach, a boardwalk, plenty of sun and sand...and the cutest boy Stacey has ever seen! Mary Anne thinks that Stacey should leave Scott alone and focus on the Pike kids, but Stacey's in love. Looking for reasons to hang around his lifeguard stand takes up all of her time, which means Mary Anne has to do the job of two baby-sitters.

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 together....

When Kristy sees how much her little brothers and sisters want to play on a softball team, she organizes a ragtag team of her own. They may not be champions, with Jackie Rodowsky, walking disaster, on the team, but at least they have team spirit! Now Bart's Bashers have challenged Kristy's Krushers to a game. The Bashers really are lean and mean...but the worst part of it all is that Kristy has a giant crush on the Bashers' coach.
