How can a child suddenly start speaking a language no one around them uses? This Mind the Kids episode, “When language surprises – unexpected bilingualism in autism” dives into the striking phenomenon of autistic children spontaneously acquiring and using a language that is absent from their home, school, and social world.

Drawing on new research, host Mark Tebbs speaks to David Gagnon, and Dr. Alexia Ostrolenk, on this topic, and their JCPP paper. With minimally speaking autistic children, the discussion explains what unexpected bilingualism is, why it challenges traditional ideas about the role of social interaction in language learning, and how it can reveal an alternative pathway into language. Listeners will hear how parents first notice these surprising language skills, why they may be both confusing and hopeful, and what this means for supporting communication and designing interventions.

The episode offers clear take home messages for families, educators, and clinicians on recognising hidden abilities, following a child’s interests (from letters and numbers to YouTube subtitles), and rethinking “plateau” periods as times of invisible but important development.
