Bangla at home, English at school: does it cause speech delay?

Many children in Bangladesh hear Bangla at home, English at school or on screens, and sometimes a regional dialect or Arabic as well. Parents often worry that this will confuse the child or delay speech. The evidence is reassuring: learning two languages does not cause language delay.

What is normal for bilingual children

• Mixing languages is normal. A child may use an English word in a Bangla sentence. This is called code-switching, and adults do it too.
• Count words in both languages. A child may know “water” in one language and “pani” in the other. Together, their vocabulary is usually similar to that of children who speak one language.
• One language may be stronger. The language a child hears most often usually develops first. That can change as life changes.

How to support both languages

• Keep speaking the language you know best. Children learn most from rich, natural talk. A parent who stops speaking Bangla to use simple English often ends up using fewer words overall.
• Give each language real use. Stories, songs, play and daily routines in each language matter more than drills.
• Do not punish mixing. Simply repeat the sentence back in the language you are using.
• Read in both languages if you can. Bangla picture books and rhymes build the same skills as English ones.

When to ask for advice

A language delay in a bilingual child shows up in both languages, not just the newer one. If your child is not meeting communication milestones in either language, is hard to understand for their age, or has lost words, speak with a doctor or a qualified speech and language professional. Tell them which languages your child hears and uses, so the assessment is fair.
