Back Cover Summary

Mary Anne has never been a leader of the Baby-sitters Club. She's left that up to Kristy... or Claudia... or Stacey. But now there's a big fight among the four friends, and Mary Anne doesn't have them to depend on anymore.

It's bad enough when she's left alone at the lunch table at school. But when she has to baby-sit a sick child without any help from her friends, Mary Anne knows it's time to take charge.

The Baby-sitters Club is going to fall apart unless somebody does something — fast. Maybe it's time for Mary Anne to step in and save the day!

Main Plot

During a meeting of the Babysitters Club, Mary Anne and Kristy are both available for a job baby-sitting Karen and Andrew. Mary Anne lets Kristy have the job. Mrs. Newton calls needing a sitter for Jamie and Lucy. Kristy takes the job without bothering to check who is available. Claudia then calls her a job hog. Stacey then points out to Claudia that she does it lots of times, and before you know it, all three are at each others' throats. Stacey reminds everyone that she's from New York and doesn't need shy little babies (Mary Anne), stuck-up job hogs (Claudia), and bossy know-it-alls (Kristy) as friends.

This causes Mary Anne to cry. Kristy then tells her to shut up and calls her a crybaby. Mary Anne then snaps and calls everyone mean names and runs home and cries. She then angrily prepares dinner for herself and her father. Her father then comes home and they ask God to watch over Alma (Mary Anne's deceased mother). Then she escapes to her room and decides not to tell her father about the fight. She thinks about calling Claudia, since Claudia didn't say anything mean directly to her. She is, however, not allowed on the phone after dinner. When she is ready for bed, she tries to apologize to Kristy using the flashlight code that they use. Kristy simply pulls her shade down. Then Mary Anne realized how angry Kristy was.


After the BSC makes up, Mary Anne asks Dawn to join The Baby Sitters Club, and she accepts! Will Dawn be a good club member? Is she responsible enough? Nothing Dawn can't prove! Mary Anne and Dawn also discover that their parents knew each other in high school and they dated! Can Dawn and Mary Anne rekindle the love that they shared that ended tragically?

Continuity and Inconsistencies



  • Mary Anne tells Dawn that her mother grew up in Maryland. But in every other book where Mary Anne’s mother is talked about, it’s said that she grew up in Iowa.
  • Mary Anne says that Kristy was too upset to go to school the day after her parents announced that they were getting divorced. But in Kristy's Book, in the third section (On Our Own), it’s said Patrick left Elizabeth when he just didn’t come home from work one day. Elizabeth called his boss, who told her that Patrick quit his job and moved west.
  • When Mary Anne has the party at her house with the girls they make Stacey a hamburger since she "can't eat the processed cheese in pizza because of her diabetes" yet she still has pizza multiple times later in the series. However, this really reflects the changes in diabetes research and treatment over time.
  • In early editions of the book, Alma's name is Abigail instead.
  • In chapter 13 when Mary Anne asks Richard if he knew Sharon, he says he did. He says that after college she moved to California and they lost touch. But other books say that Sharon‘s parents sent her to college in California to get her away from Richard because the Porters didn’t approve of him.
  • In chapter 8 when Mrs. Newton calls for a sitter, she asks if Mary Anne will check with Kristy first. In other books, it’s club policy that clients can’t request a specific sitter. Watson also requests Kristy as his sitter, and the rule is ignored. However, earlier in the book, it’s said that Kristy is first choice to sit for Karen and Andrew since she’ll be their stepsister soon.

Differences in the Reprints

  • Mr. Prezzioso initially pays Dawn and Mary Anne ten dollars each in the 1987 and 1995 novels. In the 2020 novel he pays them double what the BSC normally charges

Ann M. Martin's Dear Reader letter

Dear Reader,

In Mary Anne Saves the Day, the members of the Baby-sitters Club face their first real emergency. When Mary Anne realizes that Jenny is running a very high fever, she calls 911. If you’re a baby-sitter, or planning to be one, it’s important to find out whether you can call 911 for help in your community. If you can’t, you should find out what numbers to call to reach the police, or in case of a medical emergency, or fire. Remember, in any emergency, try to stay calm and don’t be afraid to ask for help.

When you’re baby-sitting, you’ll always feel better if you’re prepared. A great way to get prepared is to take a course in baby-sitting. Check in your town to see if any are offered by your hospital, YMCA, or Red Cross. Ask your school nurse or teacher for information. If you want to read about baby-sitting emergencies, look in your local bookstore or library for The Baby-Sitters Club Guide to Babysitting.
