Abby often speaks to her mother on her wand phone; while the character has not directly appeared in person on Sesame Street, her purple hands are shown in a point-of-view shot tucking Abby into bed in the resource video Little Children, Big Challenges: Divorce.
In the 2012 resource video Little Children, Big Challenges: Divorce it is revealed that Abby's mother and father are divorced. Abby spends part of her time living with her mommy at her house and part of her time living with her daddy at his house. Although Abby's parents are no longer married and live in different houses, Abby learns that they both still love her.
Abby's mother was first seen on screen in a series of videos produced for Sesame Street in Communities in 2018, where she was performed by Jennifer Barnhart. Previously, only her fuzzy pink hands were seen in Little Children, Big Challenges: Divorce.
