The Baby-Sitters Club Wiki

Mary Anne Breaks the Rules is the 79th book in The Baby-Sitters Club series.

Back Cover Summary[]

Since Mary Anne has been sitting for the Kuhn kids, she's noticed how much Jake misses his divorced dad. Mary Anne thinks Jake needs a guy to hang around with...but she doesn't want to tell Mrs. Kuhn this. So Mary Anne invites Logan over to play with Jake while she's baby-sitting.

Everything's perfect — until one day Mrs. Kuhn comes home early and finds Logan there. It's just a misunderstanding, but all Mrs. Kuhn and Kristy see is that Mary Anne has broken the number one rule of baby-sitting. She's invited her boyfriend over. What will happen to the BSC when their other clients find out?

Summary[]

Subplot[]

Clients team up and make haunted houses around the neighborhood. Jake Kuhn, Buddy Barrett, and Nicky Pike create a scary and funny house in the Kuhn Family's basement. Vanessa Pike, Matt Braddock, and Haley Braddock create a scary haunted house in the Braddock Family's basement. Each group goes to war with each other to see who can get the most customers. Vanessa, Matt, and Haley's group had the scarier one when Mary Anne Spier polled the kids that went to both.

Ann M. Martin's Dear Reader Letter[]

Dear Reader,

You may have noticed that Halloween is often a theme in the Baby-sitters Club books. When I was younger, I loved Halloween. It was a very big deal. We usually had a class party and a parade in school. Then we would come home, and as soon as it was dark, my friends and I would go trick-or-treating. When we were very little, our parents came with us. We couldn't wait to go by ourselves. For many years, Beth McKeever, my sister Jane, and I would go trick-or-treating together. We went up and down every street in our neighborhood. Some years, we would each come home with an entire grocery bag full of candy. If I rationed mine, I could make it last until Christmas.

Of course, before Halloween, we had to make our costumes. We almost never bought them. When I was in sixth grade, I decided to be a leprechaun, and I sewed the costume by myself. In seventh grade, I dressed as a hippie. I can't remember my earlier costumes, but I do remember that one year, my sister and her friend Cathy dressed up as Raggedy Ann and Raggedy Andy. After I got too old to go trick-or-treating, I liked handing out the candy instead. And I still do.

Trivia[]

  • Mr. Ohdner calls for a sitting job in chapter 10.
  • One goof includes: when Kristy is baby-sitting at the Barretts' house a bunch of kids come over including the Kuhns. They begin discussing creating a spook house and Jake Kuhn says they should have it "Here, because his mom won't mind." Of course his mom won't mind if it's at Buddy's house! I know eventually the houses are held at the Kuhns and Braddocks but that was not how it started.
  • The Prezzioso's call for a job.
  • Mary Anne always wants to say yes to salespeople when they visit
  • Shannon narrates chapter fourteen.
