She made her first appearance in the video Little Children, Big Challenges: Incarceration, where she mentions that, like Alex, her father was incarcerated. A flashback shows Sofía as a child, coping with her feelings by talking with her mother (played by Desiree Elle), drawing pictures, and writing letters to her father.
Sofía has reappeared in online videos produced for Sesame Street in Communities initiatives, and is depicted in companion digital storybooks. She features most prominently in two series of videos focusing on traumatic experiences (2017) and homelessness (2018). In the latter, it is revealed that Lily's family is staying with Sofía while they search for a new permanent home.
