Why speaking two languages at home can actually benefit a child with autism

Nearly two-thirds of the world’s population speaks two or more languages 1, and more than 350 different languages are spoken across the U.S.2 Bilingual children typically follow the same developmental language milestones as children learning only one language.3

When parents continue to speak to their children in their home language, they give children the rich language models they need to make learning English even easier. How bilingual a child becomes depends on how much he hears and speaks each language in his daily life.4

But what about children with autism spectrum disorder (ASD)? Current research does not support the idea that raising a child with autism in a bilingual learning environment will delay language development or cause a language disorder. In fact, based on recent studies, we encourage parents to expose their child with autism to bilingual language environments.5 Several studies have found no differences in language skills (including vocabulary and age of early language milestones) between children with autism who are exposed to one or two languages.

Developing dual-language abilities in children with autism from bilingual families enriches communication with their parents and the formation of ethnic identities. It also increases opportunities for social interaction inside and outside the home with extended family and the community.6

At Marcus Autism Center, we’re taking steps to help support bilingual patients and families.

  1. We conduct diagnostic evaluations in the native language of the family with an interpreter or a bilingual psychologist.
  2. We provide interpreters for clinical care.
  3. We have print resources and educational information in multiple languages available.

Contact Karen Guerra, our bilingual speech-language pathologist, for more information about autism and bilingualism.
