English in early childhood: the ideal moment
No adult learns a language with the ease of a young child. It is not talent — it is biology. And this is exactly the right period to begin.
Why so early?
In the first years of life, the child's brain is building the circuits of language. At this stage, they do not "study" a language — they absorb it, just as they absorb their mother tongue: listening, playing, living. It is what Maria Montessori called the absorbent mind.
The capacity to distinguish and reproduce the sounds of any language peaks in early childhood and declines with the years. That is why those who start early speak without an accent and without effort — while those who start late study for years to achieve less. See the science of sensitive periods.
The opportunity cost: free now, expensive later
Here is the argument almost nobody makes — and it may be the most important one. In early childhood, English comes built into life: in the circle-time song, at snack time, in playground games. It does not take a single extra hour of the child's routine. The cost, in time and effort, is practically zero.
A few years later, everything changes. The older child's schedule fills up — sports, music, homework, friends, social life. English stops being something you live and becomes one more activityto fit into the week: an extra class, a separate course, a time slot competing with everything else the child also wants to do. It costs money, costs hours, costs willpower — and still delivers an inferior result, with more effort and almost always with an accent.
A bilingual brain is a stronger brain
The gains of early bilingualism go far beyond speaking two languages. Researcher Ellen Bialystok, one of the world's leading authorities on the subject, showed that the bilingual brain is constantly solving an invisible question — "which language do I use now?" — and that this ongoing exercise strengthens executive function: the set of skills that governs focus, self-control and the organization of thought.
- Inhibitory control: to speak one language, the brain must "hold back" the other. It is the same mental muscle that helps a child concentrate and resist distraction.
- Working memory: keeping two systems active at once trains the capacity to hold and manipulate information — the basis of reasoning and mathematics.
- Cognitive flexibility: switching between languages is switching between ways of seeing the world. Those who do it from early on think more nimbly.
- Language awareness: understanding that the same thing has two names awakens an early sense of how languages work — and makes the third and fourth languages easier.
Executive function predicts school and career success better than IQ itself — and, like every foundational skill, it is built most easily in the first years. It is the "skills beget skills" principle: the earlier this base is built, the more everything that comes later rests on it.
The world's knowledge is in English
There is a practical, and enormous, reason that is often forgotten: English is the language in which the world thinks and shares what it knows. The most advanced science, medicine, technology, aviation, international business, the best of the internet — all of it happens, first, in English.
A child who grows up fluent will not depend on second-hand translations or subtitles. They will have direct access to the source: they can study at the world's best universities, read the original paper, watch the expert's lecture, work with people from any country. English stops being a subject to conquer and becomes a key — the one that opens the room where real knowledge circulates.
Real immersion, with native and bilingual teachers
An English class once or twice a week does not create bilingualism — it creates memorized vocabulary that vanishes over the holidays. What works is immersion: the language present in the routine, every day, in real situations.
At Escola Montessoriana, children are surrounded by English every day in the voices of fluent teachers — native speakers and bilingual Brazilians. The language shows up in games, in songs, at meals, on the playground — exactly the way their mother tongue entered their lives. No pressure, no tests, no "now it's English time". The language simply becomes part of life.
And it must be real people: Patricia Kuhl's research showed that babies learn the sounds of a new language from a present, interacting person — and learn nothing from watching the same content on a screen, alone. That is why live immersion, with real people interacting every day, makes all the difference — and no app can replace it.
And we don't stop at English
Families who wish can choose one more language for their child: French, Mandarin, Spanish, Italian or German. The same immersion logic applies to the third language — and the same early-childhood window too. The earlier it starts, the more natural, effortless and lasting it is. That is what makes us a truly trilingual school: Portuguese, English, and a third language chosen by the family.
