Many parents raising bilingual or multilingual children experience the same frustrating situation.
You speak to your child in the target language every day. For years. They understand you perfectly well – yet they still reply in English. Or perhaps they barely respond at all.
Meanwhile, you see other families whose children speak the minority language effortlessly. Naturally, you begin to wonder:
What am I doing wrong?
If this sounds familiar, you’re not alone. In fact, this is one of the most common challenges families face when raising bilingual children.
In this article, I’ll explain why this happens – even when parents are doing everything “right” – and share a proven framework that has helped many families move from passive understanding to active bilingualism.

The situation many bilingual families face
Let me start with a story.
Last week I attended a Chinese New Year gathering with several other Chinese families. One of the mums had a three-year-old daughter. Both parents were Chinese, and they spoke Chinese to her at home. Yet the little girl only spoke English, even though she understood some Chinese.
At one point my daughter came up to me and said something in Chinese. The mum looked surprised and asked:
“Your daughter actually speaks to you in Chinese? How do you do it?”
I could immediately sense the anxiety behind that question.
In the nine years that my Russian husband and I have been raising our children to be trilingual, I’ve seen this situation again and again.
The parents are doing many things right:
They speak the minority language consistently.
They’ve been doing it for years.
Their child understands the language fairly well – maybe 60% or even 80%.
Yet the child rarely initiates using the language and almost always replies in English/ the majority language of the country they live in.
Parents in this situation often feel:
frustrated
self-conscious around other bilingual families
worried that they’ve somehow “missed the window”
Many parents hope their child will eventually 'grow out' of this phase and start speaking the language spontaneously.
I understand this feeling very well.
Because I’ve been there myself.
Passive bilingualism: an often misunderstood outcome
Before jumping straight to solutions, it’s important to clarify something.
By some definitions, the child in the example above is already bilingual.
This is known as passive bilingualism – when a child understands a language but does not actively speak it.
And there is nothing inherently wrong with that outcome.
In fact, passive bilingualism is extremely common. For many families, it works perfectly well. The child can understand conversations between adults, follow instructions, and communicate with relatives to some degree.
Later in life, if the child decides to learn the language properly, their prior exposure can make that process significantly easier.
So passive bilingualism is not a failure.
However, most parents who say they want to raise bilingual children are usually hoping for something more. They want their child to speak the language as well as understand it.
Often this is for very practical reasons:
grandparents may not speak English
the family might move abroad one day
parents want their child to fully participate in their heritage culture
Which raises the key question:
Why do some children remain passively bilingual for years, even when parents consistently speak the language at home?
The Exposure × Need Matrix
To understand this, we need to look at a simple but powerful concept.
In a previous video – and in my book – I explain that success in bilingual parenting ultimately depends on two factors:
Exposure × Need
I originally encountered this idea in Adam Beck’s excellent book Maximize Your Child’s Bilingual Ability. Later, based on a suggestion from one of my viewers, I began describing it as Exposure multiplied by Need, because the two factors interact with each other.
Let’s break it down.
Factor 1: Exposure
Exposure simply refers to how much language input your child receives.
This might come from:
parents
books
TV and media
school
extended family
the surrounding community
Generally speaking, exposure determines how well a child understands a language.
The more they hear a language, the more their comprehension grows.
Factor 2: Need
Need refers to something different.
It asks the question:
Does your child actually need this language to communicate?
In other words, can they function perfectly well without using it?
Need strongly correlates with speaking ability. When a child genuinely needs a language to communicate, they are much more likely to start using it actively.
Why children get stuck in passive bilingualism
When you combine these two factors, you can imagine four possible scenarios.
Low exposure + low need
In this situation, a child neither understands nor speaks the language. This is fairly straightforward.
Low exposure + high need
This scenario is extremely rare. Without input, language production cannot develop. Need alone cannot create language ability out of thin air.
High exposure + low need
This is where many families (including us!) become stuck.
A child may understand the language extremely well – sometimes up to 90% comprehension – yet still refuse to speak it.
Why?
Because humans naturally choose the path of least resistance, and children are no exception.
Imagine this scenario:
You speak Spanish to your child.
Your child replies in English.
You continue the conversation anyway.
From the child’s perspective, the lesson is simple:
“English works. I don’t need Spanish.”
Once you see it this way, the situation becomes very clear. The child is not deliberately trying to frustrate you (although it can feel that way for sure!).
They are simply using the language that gets results with the least effort.
A real-life example: mum and teenage children talking in two languages!
I once witnessed a striking example of this at Stansted Airport.
A South Asian mother was travelling with three teenage children. For about half an hour, I sat nearby while eating lunch and (nosily) observed their interaction during this time.
The mother spoke to her children entirely in what sounded like Urdu. The teenagers understood everything she said.
But every single reply from them was in English.
This continued for the entire conversation!
Unless they were deliberately speaking English in public out of politeness – which seemed unlikely – it appeared that this family had been stuck in the high exposure, low need situation for years.
And that is the crucial insight:
Children do not automatically grow out of passive bilingualism.
Some do. But many do not.
I myself am a passive bilingual in Shanghainese, my mum's mother tongue. To this day, I understand it but do not speak it because... Well, there's NEVER been a real need for me to use it!
The goal: active bilingualism
The situation most parents are aiming for is the final quadrant:
High exposure + high need.
This is where children:
understand the language
speak it comfortably
and use it spontaneously without being pushed
So the real question becomes:
How do you move from passive bilingualism to active bilingualism?
The solution: fix both sides of the equation
To move forward, we need to address both exposure and need.
Step 1: Increase language exposure
For many families, this is the easier part.
Try to increase both the quantity and quality of language input your child receives.
Some strategies include:
consistently following One Parent One Language if that is your strategy
reading books together in the target language
watching TV together rather than passively
involving extended family members
enrolling in weekend language classes
If you use TV or streaming services, try watching together and discussing the content. Passive background exposure alone rarely produces strong results.
I've made a video and blog post explaining how we've incorporated Netflix into our language routine - check it out!
The key point to remember is this:
Exposure improves comprehension, but it does not automatically produce speech.
Step 2: Create genuine need
This is the harder part.
Creating real need can be challenging because the majority language – especially English in many countries – tends to dominate everyday life (I like to call it 'majority language invasion'!)
Children naturally choose whichever language gives them the fastest results.
If they can obtain everything they want in English, there is little motivation to switch.
Strategy 1: The two-minute rule
A simple and beginner-friendly way to start is what I call the two-minute rule.
For example, during breakfast tomorrow, set a timer for two minutes.
During those two minutes, your child must respond in the target language – even if it is just basic phrases like:
please
thank you
yes
no
This creates a small but important pattern interrupt. It establishes at least one situation where the target language is genuinely required.
It may seem small, but it can be the first step toward building a new habit.
Check out my video and blog post exploring this concept!
Strategy 2: The 'Bootcamp Method'
For families who need a more intensive reset, I discuss something called the Bootcamp Method in my book.
This approach involves temporarily increasing expectations that the child replies in the target language over a focused period of weeks or months.
Several parents who have read my book have told me this method was the turning point for their family. One mum even joked that the book had become her 'new bible'!!
Of course, every family is different, but many parents find that structured expectations help shift the balance from passive understanding to active speaking.
Obviously, I'd recommend purchasing my book for a deep dive into this method – you'd be supporting my work, for which I would be immensely grateful.
Otherwise, feel free to check out a video of me explaining this method.
Final thoughts
If your child understands your language but still replies in English, it does not mean you’ve failed.
In many cases, it simply means your child is stuck in the high exposure, low need situation.
Once you understand this dynamic, you can begin adjusting both sides of the equation.
Increase meaningful exposure.
Create genuine need.
And over time, many children do begin to move toward active bilingualism.
