Childhood Experiences

Abby is 8 minutes younger then Anna in Abby and the Best Kid Ever.

She moves to Stoneybrook from Long Island. Abby's father was killed in a car accident (he was hit by a dump truck and died instantly) when Abby was nine. She remembers finding out about the accident in school. After her father died it felt wrong to laugh and to be alive, until one day she found herself laughing and realized it was okay. In Long Island the middle school principal had a British accent, a huge pot belly and a tendency to twist his hair into knots whenever he spoke.

She was the star forward, leading scorer, and co-captain of the soccer team. They had a housekeeper in Long Island. The Stevenson family used to go up to Lake Placid every winter to ski.

Abby and Anna's mother did not allow them to play with their food as children.

She was in the Girl Scouts until her dad died.

In Abby's Un-Valentine, she once bought a heart shaped box with Anna to give to their parents for Valentine's Day. Abby ate the entire box after staring at it for so long. She got a stomach ache and couldn't eat dinner that night. She mentioned in fifth grade Perk Watkins followed her around with candy hearts causing the kids to laugh at her. She came down with a cold and when she came back to school, he liked another girl in her place.


In Abby and the Best Kid Ever she mentioned that she pitched a fit about not wanting to move from her home in Long Island, which her mother wanted to do in order to take a promotion. She ended up liking Stoneybrook more than she thought.

When the BSC took a cross country trip (Super Special #14 BSC in the USA), Abby chose to visit Graceland. Going to the Grand Canyon during the trip made her very sad at first because her family was supposed to take a trip out there, but her father died a few days before the trip, so it never happened.

She does not like Valentines day. Ross Brown used to like her, because he thought she was Anna in Abby's Un-Valentine.

Abby wakes up to the Elvis Presley radio.

She met the queen of England and stepped on the prince's toe. Because of that, she was in a magazine in Baby-sitters' European Vacation.

In Aloha, Baby-sitters!, she was in a sunscreen commercial.

In Abby the Bad Sport, she played on a soccer team partnered up with disabled kids. One of her good friends outside of the club is Erin. In Long Island, her best friend was Elvira.

In Abby's Twin, it's mentioned that she went to Disney World for a week in seventh grade. It's mentioned that Abby does have a curvature in her spine but it's only at 14 degrees. She does not require a brace for scoliosis.


She has a couch in her bedroom.


Abby has many allergies and often jokes that, "Life makes me sneeze." She counts on outgrowing many of them when she's older. Her allergies are always worse in times of stress and hay fever season. Her allergies and medical conditions includes:

  • Asthma: she has gotten used to it, often looks worse then it is. She has two inhalers, a regular one and an emergency one. Abby's had a couple of attacks before but nothing that couldn't be fixed in the emergency room.
