Does Bilingualism Delay Speech? Myths vs. Facts

One of the most common worries I hear from Russian-speaking parents in South Florida: "Are two languages confusing my child? Should we drop Russian at home?" The short answer is no, and the research is remarkably consistent on this.

Myth 1: Bilingualism causes speech delays

Bilingual children hit major language milestones (first words, two-word phrases) on the same overall timeline as monolingual children. Their vocabulary is distributed across two languages, so counting only English words underestimates what they actually know.

Myth 2: Mixing languages is a red flag

Code-mixing ("Дай мне the ball") is a normal, healthy part of bilingual development, not a sign of confusion. Children learn to separate languages by context as they grow.

Myth 3: Dropping the home language helps

The opposite is usually true. A strong first language is the foundation the second language builds on, and it keeps children connected to grandparents, culture, and identity. If a child has a true speech or language disorder, it will show up in both languages, and therapy should address both.

When to check in with an SLP

If your child is not combining words by age 2, is hard to understand at 3, or you simply have a gut feeling something is off, a bilingual evaluation looks at both languages together and gives you real answers instead of guesses.
