SAN FRANCISCO (CBS SF) — A Bay Area mother of a child with Down syndrome and a big fan of animated Disney movies has gathered tens of thousands of signatures in a petition urging the studio to show characters with Down syndrome as heroes.

Keston Ott-Dahl, who has a 15-month-old daughter with Down syndrome, told the Orlando Sentinel that her child has no real Disney role models to relate to in her favorite animated films, such as the Academy Award-winning “Frozen.”
