It is fascinating how many people have misconceptions about bilingualism and its effect on a child’s delay in speaking. People repetitively ask questions like these:
- Won’t kids be confused learning two languages at once?
- Won’t being bilingual or teaching a child more than one language cause speech delay?
- Would you ever be fluent in a language if you don’t learn a language at an early stage?

Bilingualism causes speech/language delay
THAT IS A MYTH!
While a bilingual child’s vocabulary in each language may be smaller than average, his total vocabulary, from both languages, will be at least as large as that of a monolingual child. Bilingual children may say their first words slightly later than monolingual children, but they will say them within the normal age range (8-15 months).
When bilingual children begin to produce short sentences, they develop grammar in the same patterns and timelines as monolingual children. Language delay is not caused by bilingualism. A bilingual child who is experiencing significant delays in language milestones may be suffering from a language disorder and should be evaluated by a speech language pathologist.

Another common misunderstanding about bilingualism is the assumption that one is incapable of being fluent in a language they did not learn in their “early stage”.
According to the “Critical Period” theory, there is a window of time (early stage) when a second language is most easily learned. This theory has led many people to believe that learning a second language as a child is preferable. However, some findings have put this theory into question. Therefore, the fact that one might not be “fluent” in a language because they learned it later on in their life, is FALSE.
Overall, there are many misconceptions when it comes to the effects of being bilingual, and these misconceptions vary widely. It is advised to verify our assumptions by doing some research, so we do not fall into this trap!
