My spouse and I speak different languages at home. Does it affect my autistic child’s speech negatively?

Many parents wonder whether speaking two languages at home will delay their autistic child’s speech. Current research suggests that being exposed to more than one language does not cause or worsen autism or language delays. In fact, children with autism are capable of learning more than one language, just like many other children.

The most important thing is for each parent to communicate in the language they are most comfortable speaking. This allows for more natural conversations, stronger emotional connections, and richer language experiences. Limiting your family to one language may actually reduce opportunities for meaningful communication, especially if a parent is less fluent in that language.

Every child develops at their own pace, and some autistic children may need additional support with communication regardless of the number of languages spoken at home. If your child is receiving speech or ABA therapy, let the therapy team know which languages are spoken at home so they can help support communication across both languages.

The goal is not for your child to speak one language perfectly, but to build meaningful communication with the people who matter most. Speaking the languages that are part of your family’s everyday life helps your child stay connected to both family and culture while continuing to develop communication skills.
