Should I Only Speak English at Home if My Child Has a Speech or Language Delay?
Research does not support the idea that exposure to multiple languages causes or worsens a speech or language disorder. Children with communication disorders can learn more than one language.
This does not mean that every family needs to raise their child bilingually. Families may choose which languages to use based on their own circumstances, relationships, and priorities. However, a speech or language delay alone is not a reason that a family has to stop using a home language.
Does bilingualism make a language delay worse?
No, learning more than one language does not cause a speech or language disorder, and multilingual development should not automatically be interpreted using monolingual expectations.
I've written more about this in What is Normal in Bilingual Language Development?
Should we switch to English at home?
Not necessarily.
One consideration is the quality of language input a child receives. Parents generally communicate most naturally and with the greatest linguistic complexity in languages they know well.
For example, a parent who is much more proficient in Mandarin Chinese than English may be able to provide a richer language model in Mandarin Chinese. Switching entirely to English does not automatically provide a child with “better” language input simply because English is the dominant language in the community.
For that reason, I generally do not view “use only English” as a treatment for language disorder.
Instead, decisions about language use should consider factors such as:
which languages family members speak most proficiently;
which languages the child needs to communicate with important people in their life;
how much exposure the child receives to each language;
where and with whom the child uses each language; and
the family's own priorities for multilingualism.
What does this mean for speech therapy?
Speech therapy for a multilingual child does not necessarily need to target every language equally. I consider which language or languages the child understands and uses most successfully, where they have the strongest language foundation, and which languages they need in their everyday life.
A child's dominant language can also change over time as their exposure and environments change. A child may primarily use Spanish or Mandarin at home, for example, and gradually use more English after beginning school.
When a child has a language disorder, one goal is to help them develop a strong foundation for language learning rather than treating each language as an entirely separate system. Skills and concepts developed in a stronger language can support learning in another language, although transfer will not look the same for every skill or every child.
This is why I don't automatically approach multilingual speech therapy as “English versus the home language.” I look at where the child already has linguistic strengths, what they need to communicate in their daily life, and how we can build from that foundation while continuing to support their other languages.
The Decision Belongs to Your Family
You do not need to stop speaking your home language solely because your child has a speech or language delay.
Children with communication disorders can learn more than one language. Families are the ones that decide what language use works for them based on their communication needs, relationships, culture, and priorities.
A communication disorder doesn't make that decision for your family.
