The London Nursery Revolution: Teaching Three Languages Before Age Three

On a typical Tuesday morning, you might hear something unexpected when you walk into Moreton First’s preschool wing: a group of three-year-olds singing along enthusiastically to a French children’s song about a very hungry caterpillar. They are not being drilled. There are no stern-looking people holding up flashcards. All they’re doing is singing. They are also learning French in some way.

From the inside, the London nursery revolution looks like this. Instead of whiteboards and worksheets, kids are organizing imaginary groceries while a teacher models Spanish vocabulary in the home corner and Bob le bricoleur appears on a projector screen. It’s intentional. It has been studied. And the majority of educators believed it was useless for a long time.

For years, the belief that teaching a foreign language to children under five was essentially a waste of everyone’s time was held with surprising confidence. It was believed that young children were still struggling with their mother tongue. It seemed almost cruel to add more languages—cognitively ambitious in a way that would produce nothing. That presumption hasn’t held up well over time. Conversely, Harvard University longitudinal research indicates that early language acquisition enhances critical thinking, fosters creativity, and develops mental flexibility that lasts well into adulthood. It’s interesting to note that students who acquire a foreign language prior to formal education routinely outperform their peers in verbal and math assessments. Learning a language is more than just practicing language. It’s a mental one.

The attitude at Moreton First is almost disarmingly informal. The kids come across four languages when they are three years old. Naturally, English comes first; it is developed through role-playing, songs, stories, and everyday rhythms. Then comes French, which is so subtly incorporated into the narrative that many kids don’t realize they’ve switched. Next, a teacher known to the kids as “Mr China” shows up with games and props and introduces Mandarin through play-based activities that, at least to the kids, seem like just another game. In a matter of weeks, tiny voices are trying “Ni hao” with a degree of assurance.

Spanish, on the other hand, resides in the home corner, with labels on the shelves, a fluent teacher close by, and conversations that occur almost unintentionally while kids create their own imaginary worlds. Observing this gives the impression that the adults are putting in a little more effort than the kids. The kids are merely having fun.

It’s getting more difficult to ignore the science behind it. Harvard Medical School physician Dr. Pascual-Leone has been studying the connection between bilingualism and brain aging. He has discovered early signs that learning a second language may provide some protection against cognitive decline in later life. A three-year-old learning to count in Mandarin today might be contributing to the development of resilience for decades to come. It’s a powerful idea to think about.

The political machinery has been moving in the same direction, albeit more slowly, since returning to power. The UK’s expansion of free nursery spaces, which started with 41,500 spots spread across 57 inner-city local authorities, represents a wider understanding that early childhood education is important in ways that were previously underappreciated. In short, half of a child’s intellectual development occurs before the age of five, according to Margaret Hodge. She contended that the traditional division between play and education is no longer relevant. Seeing a child correct a classmate’s French pronunciation during what is supposed to be free play makes it difficult to disagree.

The rate of change is unsettling to some. Concerns have been voiced by groups like the Pre School Learning Alliance regarding the possibility that younger and younger kids are being subtly pushed toward formal education before they’re ready. These worries are not irrational. There is a real and significant difference between pressure and enrichment. However, the more considerate nurseries in London don’t appear to be under pressure. Children appear to be doing what they have always done, which is to take in their surroundings. However, this time, the surroundings include some Mandarin.

Researchers consistently find that learners are more adept at internalizing pronunciation patterns and mimicking sounds when they are younger. Before adolescence, the brain is remarkably receptive to new language. It appears that nurseries in London are finally taking notice of that window before it closes.
