The Baby-Sitters Club Wiki

Karen Brewer is the seven-year-old daughter of Watson Brewer and Lisa Engle. She is the older sister of Andrew Brewer and the stepdaughter of Elizabeth Thomas-Brewer and Seth Engle. Karen is a member of both the Engle Family and Brewer/Thomas Family. She is the narrator of the Baby-Sitters Little Sister series. Karen is a fearless, smart girl with a wild imagination that can sometimes get out of hand.


Karen is described as having long blonde hair, blue eyes, and freckles, and she wears glasses (she has blue glasses for reading and pink glasses for everything else). She is frequently seen in her pink shirt with a unicorn on it.



Karen is the stepsister of Kristy Thomas, who is one of Karen's favorite people.

Karen was born on a warm spring day at 2:35 in the afternoon in Karen's Book. Lisa and Watson did not know Karen's gender until she was born, and they named her Karen because it means pure. Watson felt pure joy when he saw his daughter the first time.

Karen describes herself and her brother Andrew Brewer as "Two-Twos" (that she got from a book called "Jacob Two-Two Meets the Hooded Fang") because they split their time between the "little house" (which is their mom's house) and the "big house" (which is their dad's house).

Karen and Andrew tend to have two of most things since they spend a lot of time at each of their parents' houses.

She is in the second grade in Ms. Colman's class at Stoneybrook Academy. She is a very smart girl and reads a lot. When she began kindergarten, she was put in the first grade during Christmas. However, later books describe the skip as being from first to second grade after about a week in the former.

When she was younger, Karen attended Little Friends Day School where her teacher was Ms. Herman.

The Baby-Sitters Club

In the book "Little Miss Stoneybrook ...and Dawn," Kristy helps Karen enter the Little Miss Stoneybrook pageant. The pageant is for girls ages five to eight. During the pageant, Karen wears the dress that she wore in her father and stepmother's wedding. For her talent, she sings "The Wheels on the Bus," but she added so many extra, made up verses to the song that the judges began looking at their watches because she took too much time.

For the interview part, Karen was asked "If your house was on fire and you could only rescue three things, what would they be, and why?" Karen had practiced the questions with Kristy and knew what she was supposed to say (nice answers like saying she would rescue her family), but instead, she said she would rescue her toys and her blanket. Karen did not win anything in the beauty pageant, so she was sad and cried.

She was in Kristy's group when the BSC took their clients to Sudsy's Carnival in Kristy and the Mother's Day Surprise.

In Starring the Baby-sitters Club!, she gets the part of Tinkerbell in SMSs production of Peter Pan. Mr. Cheney gave her the part when she begged and threw a tantrum about it.

Karen was the flower girl at both her parents' wedding, shown in Kristy's Big Day and Karen's Book.



  • She used to be friends with Amanda Delaney, until the Delaney family moved away to another neighborhood. Hannie does not like Amanda.


  • Karen has a rat named Emily Junior who travels with her between her two houses.
  • Karen found a cat named Growly in her shed and adopted it in Karen's Kittens. Growly left once her kittens were grown and adopted out.
  • She and Andrew have goldfish named Crystal Light the Second and Goldfishie that live in a tank in the playroom at Watson's house. Karen used to have a goldfish named Crystal Light, but it passed away while she was at her mom's house.
  • Watson adopted a pony named Blueberry for Karen after visiting an estate sale. Since he can't live at the Brewers' house, Watson pays to board him at a nearby farm. In Karen's Pony Camp, Blueberry is sent to the camp where she stays.
  • Karen nurses an orphaned baby sparrow, whom she names Magic Tastee, back to health in Karen's Little Sister.


  • Karen has two stuffed cats named Moosie and Goosie (who look exactly the same). Goosie stays at the "little house," and Moosie stays at the "big house."
  • After her stepfather Seth Engle accepted a job in Chicago, Goosie moved with Karen to her dad's house for the duration.
  • She has a blanket named Tickly that she ripped in half so she could keep one piece at both her mother's and father's houses.
