Long Island, NY
Abigail "Abby" Stevenson is an alternate officer in The Baby-Sitter's Club. Abby has a twin sister named Anna Stevenson. Her father died in a car accident when she was nine years old. Abby has long, curly dark brown hair and brown eyes (she wears contacts), while Anna has short dark brown hair and brown eyes (she wears glasses). The twins look a lot like their mother. Abby and Anna were born on October 15th. It is not known what time Abby and Anna were born at or what hospital they were born at. Abby made her first appearance in Book #89 Kristy and the Dirty Diapers. She became the alternate officer of the BSC in book 90, a position she held until the end of the regular series.
Abby originally lived with her parents and twin sister in Long Island, New York, but moved onto McLelland Road in Stoneybrook, Connecticut when she was 13. Abby's father was killed in a car accident (he was hit by a dump truck and died instantly) when Abby was 9. She remembers finding out about the accident in school. As a child, their mother did not allow Abby and Anna to play with their food.
Abby has many allergies (dog hair, cat hair, litter, etc.) and often jokes that "Life Makes me sneeze." She has severe asthma and carries an inhaler around with her. Abby is very close to her mother and sister, but doesn't like to talk about her father much. Abby is like her father with a silly side and a good sense of humor. She is also very outgoing and athletic. Soccer is her favorite sport. She and Kristy have similar personalities, which has led to a variety of clashes. Sometimes she gets annoyed at her sister's constant music playing. Abby is also Jewish and celebrated her Bat Mitvah with her sister. Abby also loves music (especially Aretha Franklin and Elvis Presley). When the BSC took a cross country trip (Super Special 15), Abby chose to visit Graceland.
Anna was asked to join the Baby Sitters Club along with Abby (who accepted), but was too busy with her music, since she plays the violin and is in the SMS orchestra and wouldn't have time for both. This is the first time someone had declined an invitation to the Baby Sitters Club (besides Logan Bruno).
Abby's mother is a book editor and commutes to New York every day for work. Thus, Abby and Anna learned at a young age how to order take out on their own.
Abby had trouble laughing after her father died because he had a sense of humor and laughed a lot and every time she laughed, she thought of him. Going to the Grand Canyon (Super Special 15) made her very sad at first because her family was supposed to take a trip out there but her father died and the trip never happened.
