There is a moment a lot of families abroad recognise. You ask a question in your language. Your child understands it perfectly — and answers in English.

This is so common that it has a name among people who study language at home: receptive bilingualism. The child understands far more than they produce. It is not a sign that the language is lost, and it is not a sign that anyone did anything wrong.

Why it happens

A child spends six or seven hours a day in a language that is not yours. School runs in English. Friends run in English. Cartoons, games and playground negotiations run in English. Their vocabulary for the things that matter most to them at eight years old is in English, because that is where those things happened.

Meanwhile the home language often covers a narrower range: meals, affection, instructions, relatives. A child can be completely fluent in being loved in Telugu and have no words at all for what happened in football.

Understood that way, the problem is not motivation. It is that the home language has fewer rooms in it.

Build rooms, not drills

The instinct is to correct more, or to insist on replies in the home language. In many families that turns the language into a site of conflict, which is the one thing you cannot afford — a language a child associates with being told off is a language they will avoid.

What tends to work better is giving the language more to do.

  • Stories add rooms. A story has weather, animals, arguments, journeys, a grandmother who disapproves of something. That is vocabulary a child will not get from "have you eaten?"
  • Let them answer in English for now. If you keep speaking your language and they keep answering in theirs, the conversation continues, and the input keeps arriving. Input is what builds the understanding that production later grows out of.
  • Find the one topic that belongs to the language. In a lot of families it is cooking, or a particular grandparent, or festivals. Whatever it is, do not translate it. Let there be subjects that simply happen in your language.

Why a grandmother's voice is not sentimentality

There is a practical reason that a grandparent's recording works where an app often does not.

It carries the register a child actually needs. The way a grandmother tells a story — the asides, the teasing, the small endearments — is a different kind of speech from the clean, slow, instructional voice of a language program. It is the speech of a family, and it is the speech a child will want to answer in.

It also arrives with affection attached. A child who hears Malayalam as the language of someone who loves them is in a different position from a child who hears it as a subject.

Set an expectation you can live with

It helps to decide what you are actually aiming for. For many families abroad, the honest goal is not literacy or fluent adult conversation. It is this: that when my child is thirty and sits with their grandmother, they can talk to her.

That goal is reachable with listening, affection and time. It does not require perfect grammar, and it does not require winning the argument at dinner about which language we are speaking.

If you are starting late

Families often ask whether it is too late at eight, or ten. Starting later means more deliberate effort, but "too late" is the wrong frame. People add languages at every age. What changes is that you will need to create the exposure on purpose, because it is no longer arriving by itself.

Begin with listening, choose material a child actually enjoys, and keep the language out of the discipline conversation.

What we are not claiming

We make audio stories in five Indian languages, so we are not neutral here. We are not going to tell you that listening to stories produces bilingualism on its own, because it does not — a language lives on use, and most of that use happens in your house, not in anything you can buy.

What recorded stories can do is narrower: supply more of the language, in a register worth imitating, in a form a child will accept at the end of a day. That is a real contribution. It is not the whole job.
