“Is it too much to ask my child to learn two languages at once? Would they fall behind? It’s better to master one language before introducing another, right? Besides, I’m not a native French speaker myself, how will I support my little ones?”

These common concerns, while well-intentioned, are often rooted in outdated assumptions about how children learn. Decades of research in linguistics, cognitive science, and education now tell a different story: early bilingualism is a developmental advantage. The benefits of learning a second language go far beyond the need to communicate. Bilingual children often show greater cognitive flexibility, improved focus, and deeper cultural awareness.

If we continue to treat bilingual language learning as an add-on, rather than a core part of a child’s development, we risk missing one of the most powerful tools we have to prepare them for a globalised world.

Why early immersion matters

Neuroscience has given us insight into what educators have observed for generations: the early years of a child’s life are uniquely suited to language learning. According to Dr Patricia Kuhl, a leading researcher in early language and brain development, children’s brains before the age of five are especially receptive to the sounds, structures, andrhythms of language (Kuhl, 2010). This “neural flexibility” means that young learners not only absorb new languages more easily but also lay down the cognitive foundations that benefit them well beyond vocabulary.

In these early developmental stages, children are not consciously translating between two languages, they are building parallel systems of meaning. Bilingual programmes, where children are surrounded by a second language in context-rich environments, tap into this ability in the most natural and effective way. Unlike older learners, who often require deliberate memorisation and repetition, young children in immersive settings acquire language through play, interaction, and meaningful communication. It becomes part of how they think, rather than something they do.

In classrooms that embrace bilingual language immersion, especially those with students from diverse linguistic backgrounds, the results can be remarkable. Even children who enter with little to no knowledge of French begin to engage meaningfully within weeks. Children learn not only from their teachers but from each other. Peer learning reinforces vocabulary, model pronunciation, and builds confidence through collaborative interaction. This natural, social form of learning is one of the greatest strengths of early immersion education, helping children become more confident, curious, and cognitively agile.

Early immersion helps to unlock a child’s full cognitive potential. The window for this kind of effortless learning is narrow, but the impact can last a lifetime.

Addressing common misconceptions in bilingual education
While bilingual education offers cognitive, academic, and social advantages, it also comes with its share of misconceptions, particularly among parents and educators unfamiliar with the developmental nuances of early bilingualism. Understanding and addressing these misconceptions is crucial not only for easing concerns but also for creating optimal learning environments in which bilingual students can thrive.

One of the most persistent worries among parents is the belief that learning two languages simultaneously may confuse or overwhelm young children. This concern often arises from the idea of subtractive bilingualism, which assumes that learning a second language could interfere with or diminish a child’s proficiency in their first language. However, research over the last several decades has disproved this notion. In fact, Lambert (1975) introduced the concept of additive bilingualism, which shows that when both languages are supported and valued, bilingual learners experience enrichment, not loss. Far from harming their development, early exposure to two languages enhances linguistic capacity and cognitive growth. Children are not replacing one language with another but are building a broader, more flexible linguistic system.

Another frequent misconception is that bilingual children may become “confused” or develop language delays due to the exposure to multiple languages. This is a myth not supported by developmental research. In reality, infants and toddlers are neurologically wired to differentiate between languages. Studies have shown that even at six months old, babies can distinguish between two linguistic systems based on rhythm and sound (Genesee, 2002). Bilingual children can quickly learn when and with whom to use each language, demonstrating a sophisticated understanding of social context.

Much of the concern about confusion stems from “code-switching”, where children mix elements from both languages in a single sentence or conversation. To the untrained eye, this may seem like a lack of mastery, but in fact, code-switching is a normal, healthy, and even strategic part of bilingual development (Grosjean, 2010). In early immersion classrooms, children often use words from their dominant language to fill in gaps as they acquire vocabulary in the target language. This is not confusion but problem-solving in real time. When students in the classroom say, “Jeveux the red one,” they are not failing, they are growing. As their vocabulary improves, the reliance on their first language fades, and their sentences become more fluid in the second language.

Rather than suppressing code-switching, educators like myself use it as a learning tool. In my own classroom, students are encouraged to speak in French when possible, but their bilingual expressions are acknowledged and valued. This balanced approach helps students see that multilingualism is not a barrier but a powerful asset. It trains them to think flexibly, to communicate more precisely, and to appreciate different cultural perspectives.

Overcoming challenges in learning French
For many young learners, particularly those from non-French-speaking households, speaking a new language aloud can be an intimidating step. While they may comprehend much of what is said, the fear of making mistakes often inhibits their willingness to participate verbally. This reluctance is not a reflection of disinterest or inability but rather, it highlights an important emotional component of language learning that must be addressed deliberately in early immersion environments.

Stephen Krashen’s Affective Filter Hypothesis offers a powerful lens for understanding this behaviour. According to Krashen, when students feel anxious, insecure, or self-conscious, an “affective filter” rises, effectively blocking language input and impeding language acquisition. Conversely, when learners feel safe, supported, and motivated, that filter lowers, allowing language to flow in and, more importantly, back out through expression.

Hence, creating a psychologically safe classroom is key to bilingual success. In the French-English Bilingual (FEB) classrooms at the Canadian International School (CIS) Singapore, we design every element of the learning environment to build emotional security and courage. This includes intentionally small class sizes that promote strong peer relationships and encourage risk-taking in a low-pressure setting. 

Active listening and collective participation are important strategies to adopt. When I introduce new vocabulary or sentence structures, students are encouraged to listen to each other and repeat as a group. This shared verbal experience removes the spotlight from any one child, allowing them to internalise pronunciation and structure without fear. Over time, these rehearsed phrases become second nature, enabling students to build the confidence needed for spontaneous speech. 

Structured routines further ease linguistic entry points. Daily routines such as our morning greeting song accompanied by gestures and movements can transform language practice into a joyful experience. Set to familiar melodies, these songs lower barriers to participation and reinforce vocabulary through rhythm and repetition, supporting both auditory and kinesthetic learners.

Perhaps most transformative are interactive activities that allow students to step into new roles. When we read Bon appétit, Monsieur Lapin, students engaged in storytelling through role-play and even the most hesitant speakers found their voice. Stepping into character gave them the ability to emulate a rabbit, a fox, or a bird. This imaginative distance reduced their fear of making mistakes and they experienced firsthand what it means to use language for a purpose: to connect, to play, and to tell a story.

By creating a safe learning space, understanding the emotional dimensions of language learning and responding with thoughtfully designed pedagogy, we can empower children to take risks, engage meaningfully, and ultimately grow into confident bilingual communicators.

Language learning beyond the classroom
For an effective bilingual education, the role of family is central. While schools lead the instruction, it is the partnership with families that sustains language learning beyond the classroom. For many children, especially those from non-French-speaking households, the home environment can either reinforce or quietly undermine their progress. The question is not whether parents speak French, but whether schools have done enough to make them feel capable of supporting their child’s journey.

Take, for example, a recent La Chandeleur experience at CIS saw students learn to make crêpes in French as part of an exploration into food and culture. Students sang songs, narrated steps, described ingredients, and interacted entirely in French. Parents were invited to participate in their child’s class; they cooked together with their children, absorbed the language in action, and saw firsthand how bilingual learning looks and feels in context.

The key is how we design for inclusion. On top of in-class immersion, we provided parents with visual documentation materials and sequencing tools that captured their child’s learning step by step. Parents were encouraged to follow-up at home by cooking together, reusing key vocabulary,or simply listening as their child recounted the steps in French. We didn’t ask parents to teach grammar or correct pronunciation, we asked them to participate, to listen, to celebrate, and to stay curious.

The broader insight here is this: a child’s bilingual development accelerates when it is normalised, valued, and embedded in relationships. Even in households where French is not spoken, children can thrive linguistically when the language is seen, heard, and celebrated.
