Back Cover Summary[]

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.


The Baby-Sitters Club began when it was a very hot Tuesday afternoon in Stoneybrook Middle School, but when the bell rang, Kristy Thomas stood up and shouted, “Hooray!” She was glad that school was over so she could have AC. However, Kristy’s social studies teacher, Mr. Redmont told Kristy she had to write a 100-word essay on the importance of decorum.

On the way out, Kristy finds her best friend Mary Anne Spier and tells her when she will have nail polish, Mary Anne says she’ll be seventy-five when she’ll have her nails polish. Mary Anne’s mother died when she was a baby, leaving her father really overprotective of her like wearing her hair in braids, dressing like a china doll, wearing skirts and dresses, not calling friends after dinner unless if given sitting jobs and homework, her room looking like a two-year old’s room, and staying up until 9:00 PM which makes Mary Anne really shy, quiet, and always seems to cry a lot when Kristy always seems to be talkative and bossy, wearing blouses and skirts like Mary Anne, and always seems to dress up like a ten-year old.

Meanwhile Kristy forgets something and runs all the way home with Mary Anne. Mary Anne tells Kristy it’s too hot to run, but Kristy says it’s Tuesday since she has to watch her brother David Michael, or else he’ll have to babysit himself. Kristy and Mary Anne made it home and David Michael cries, saying that he’s locked out and couldn’t come in the house since, he really has to use the restroom. Kristy finds a key while David Michael says it's not the key, but Kristy uses it anyway. Just as Kristy opens the door, her dog, Louie comes out to greet her since he’s been inside since breakfast.

Kristy tells David Michael that she’s going to make lemonade and he’s happy when he uses the bathroom. Meanwhile, Kristy turns on the AC and tells Mary Anne that Mrs. Newton had called Kristy to babysit Jamie that day, but Kristy refused because she had to babysat David Michael at the same time, Kristy also asks Mary Anne if Mrs. Newton called her. Mary Anne tells Kristy maybe she called Claudia Kishi.

Claudia lives down the street from Kristy and Mary Anne. The three have been together and best friends for many years until in the sixth grade, Claudia became more into art, clothes, and boys and always seems to be on the phone or decorating her wardrobe. She also became a terrible student since she always focuses on art. Her sister, Janine is a sophomore in high school and is a real life genius with a 196 IQ. She always seems to correct Kristy, Claudia, and Mary Anne since some words are not used enough and sometimes she might say: “Kristy, you must say: ‘David Michael, you may not go outside because it’s raining.’ Instead of 'David Michael, you cannot go outside because it's raining.'" Janine’s best friend is a fourteen-year old math nerd who’s graduating high school in the Spring and her second best friend is her computer.

David Michael flushes the toilet and Kristy’s older brothers Sam and Charlie enter the house. Sam announces that they are going to play football at the Hansons’ house. David Michael has a sad face because he is too young to play football. So Kristy tells Sam that they are going to the brook and David Michael nods, saying that he wants to go. At the brook, David Michael and Louie wade in the water while Kristy and Mary Anne watch while talking. When Kristy says it’s time for dinner, they walk home. When they reach Kristy’s house, Mary Anne tells Kristy that 9:00 to do their flashlight code since Mary Anne is not allowed on the phone after dinner. Mary Anne made the flashlight code up, and hasn’t been caught once like Kristy.

While Charlie is drinking, and Sam, Kristy, and David Michael are working on a puzzle. Their mother Elizabeth comes in with pizza, which makes Kristy confused. Elizabeth is a divorced mother because her husband walked out of the family when Kristy was six-years old. Elizabeth has been working in a big company in Stamford and always supports her children so much since she feels guilty because her husband always forgets the holidays and doesn’t send child support money, still, Elizabeth still feels guilty.

Kristy tells Elizabeth why she ordered pizza and Charlie begs Kristy not to. Elizabeth always brings pizza when she tells the children a favor. Elizabeth tells everyone that Kathy, David Michael’s babysitter has canceled so Elizabeth tells everyone if they are free. Charlie has football practice, Sam has math club, and Kristy is sitting for Jamie Newton. Kristy is willing to change her mind, but Elizabeth begs her not to.

Elizabeth then makes dozens of phone calls around the neighborhood for David Michael to have a sitter. She calls Mary Anne, she is sitting for Claire and Margo Pike, she calls Claudia, she has art class, then she calls Cynthia, she had cheerleading practice. David Michael looked like he might cry. Elizabeth then calls Mrs. Newton to tell Kristy that she could bring David Michael to play with Jamie, and Kristy agrees.

Then, the idea for the Baby-Sitters Club came, and Kristy almost choked on a pizza. She could hardly wait to tell Mary Anne the great idea she had in her mind. Kristy rushed upstairs to do her essay and the Baby-Sitters Club.

And that’s how the Baby-Sitters Club began.


Kristy's divorced mother, Elizabeth Thomas, has been dating a new, rich guy, Watson Brewer, and Kristy is feeling cautious about him. He seems like a good guy, but Kristy's real father, Patrick Thomas, walked out on the family, leaving Elizabeth to look after four kids on her own, including a newborn baby (David Michael). Patrick then remarried and started a new family in California. Kristy doesn't want to get hurt again and has to decide whether to hate his guts or to open up to him, taking the chance that he'll hurt her, just like her father did to her, emotionally. Kristy must decide whether it's worth the pain to love a new (almost) father again.

Also, Stacey, their new friend, is acting mysterious and Kristy, Mary Anne, and Claudia have to find out what she's up to. At a sleepover party at Kristy's, Stacey reveals she has Diabetes from eating too much sugar. She tried to hide this because her friends teased her about it, but her friends were quick to forgive her, and they are still Stacey's best friends.

Kristy babysits for the McKeevers, which has two St. Bernards Buffy and Pinky (3 year old twins). Mrs. McKeever is out for a few days leaving her niece, Miss Hargreaves to watch the dogs. Miss Hargreaves reads the ad wrong thinking the BSC also dog-sits. Kristy gets the job, and when she gets there, she was shocked to find out that she was sitting for dogs. After that ended, Kristy came up with a new idea: The Notebook.

Claudia babysits for Jamie Newton, and his mom forgets to tell Claudia that his cousins (the Feldmans) are coming because Mrs. Newton invited her sister for an art show downtown. The Feldmans are Rosie (3), Brenda (5), and Rob (8). Rosie likes to scream and run around in circles, Brenda has the chicken poxes and is very cranky, and Rob hates girls, which led to them causing chaos. It ends when Claudia reads Peter Rabbit and Where the Wild Things Are to Jamie.

Stacey babysits Kristy's younger six-year old brother David Michael, while Kristy babysits the McKeevers' at the same time. Kristy's older 14-year old brother Sam Thomas comes in after playing a game of baseball at a friend's house. Stacey remarks that Sam has curly brown hair, blue eyes, and is very cute and funny, and they flirt with each other. The three then play a game of Candy Land. When Kristy comes home, Stacey tells Kristy that her brother is so cute, while Kristy ignores that, Stacey says her sitting job with David Michael was fine, and Kristy then tells Stacey about her idea for the notebook.

Mary Anne babysits the Brewers, because Kristy refused to since she hated Watson. Karen is 5 and Andrew is 3. Karen has started Kindergarten and will move to 1st grade after Winter Break, while Andrew is quiet and says "Yup" to everything since he is shy. Karen just started Kindergarten, but will move to 1st grade after Winter break. Boo-Boo, the Brewers' cat, has a fear of Morbidda Destiny, a witch according to Karen. When the three go outside, Boo-Boo goes to Morbidda Destiny's front yard, and the witch scares him.
