Seven-year-old Winnie Hoyt sits nestled in her mother's lap in a therapy room at Oregon Health and Science University in Portland. She's dressed in a lavender romper that sets off her soft brown eyes, and smacks her lips occasionally while her mom and her speech-language pathologist fiddle with settings on an iPad-like device hovering in her line of sight.
After some adjustments, Winnie flicks her eyes over to the right spot and the two women cheer when Moana's "You're Welcome" starts to play.
