Julia is a four-year-old girl with autism from Sesame Street, introduced in 2015 as part of the Sesame Street and Autism: See Amazing in All Children initiative. She is a young girl with bright orange hair and big green eyesA�and is friends with Elmo and Abby.
Julia’s characterization was originated by Leslie Kimmelman for the digital storybook “We’re Amazing, 1, 2, 3!” She used her own experiences as the mother of a child with autism, as well as input from research and advisers from the autism community, to inform the story.
Due to the positive response to the outreach initiative, Julia was made into a physical Muppet that debuted in episode 4715 of the show, airing on April 10, 2017. She is performed by Stacey Gordon, who also used her own experiences raising her autistic son to help inform the actions of the character. The puppet is built with two sets of arms, one of which allows Julia to flap her arms in an emotional state.
