Research shows clearly that growing up bilingual is not a disadvantage but a special opportunity for elementary school children. Between the ages of six and twelve, children’s language acquisition is especially active, and the brain processes both languages in one closely connected system. Children develop both languages best when they get frequent, high-quality input from home and school, although growing up bilingual also brings specific challenges that parents should know about.
For many children today, growing up with two languages is part of everyday life, whether because of international families, moves abroad, or parents’ deliberate choice of a bilingual school. This article explains step by step what this means for their language development, how their brain works, and how parents and schools can shape the process together.
What Does Growing Up Bilingual Mean in Elementary School?
Growing up bilingual means that a child does not learn two languages as foreign languages but uses both as natural means of communication in everyday life. In elementary school, roughly between the ages of six and twelve, this language acquisition system is in a particularly active phase.
It is important to distinguish between simultaneous and sequential bilingualism. Children who grow up with two languages from birth acquire them simultaneously. Children who first come into contact with a second language after the age of three or four, for example when they start school, acquire the languages sequentially. In elementary school, the sequential form is more common, for example when children move to an international school whose language of instruction is not their native language.
A common misconception is that bilingual children must always speak both languages equally well. In reality, a dominant language almost always develops, meaning the language that is used more often. This is completely normal and not a sign of a deficit.
How Does a Child’s Brain Process Two Languages?
A child’s brain is especially adaptable. When children acquire two languages, the brain does not store them in separate areas but processes them in one shared, closely connected language system. The language centers of the brain, above all Broca’s area and Wernicke’s area, are particularly active and well connected in bilingual children.
Code-switching is a good example. When a bilingual child switches languages in the middle of a sentence, it is not a sign of confusion. Rather, it shows that the brain is actively coordinating both language systems and choosing the most fitting word or structure for the situation. Children who code-switch usually show a high level of language awareness.
One way to picture it: the bilingual brain is like a musician who plays two instruments. Depending on the situation, the musician chooses the right instrument but can also play both at once. This constant switching and coordinating also trains cognitive skills such as controlling attention and mental flexibility.
Which Factors Influence the Language Development of Bilingual Children?
The language development of bilingual children in elementary school is not automatic. Several factors determine how quickly and how confidently children develop both languages.
Why Do the Amount and Quality of Language Contact Matter?
The most important factor is the amount and quality of input in both languages. A language that a child rarely hears or speaks will develop more slowly than one that is present every day at school and at home. Quality matters as much as quantity: conversations, reading aloud, discussions, and telling stories together build vocabulary and a feel for the language far more than passive media consumption.
How Do Motivation and Emotional Connection Affect Language Learning?
Children learn languages faster when they have an emotional connection to them. A language linked to positive experiences, friendships, or family is acquired with more motivation and more lasting results. This explains why a supportive, joyful learning environment at school has such a strong influence on language acquisition.
Does the Age of First Contact With a Language Matter?
The earlier children come into contact with a second language, the more naturally and with less of an accent they develop it. The elementary school years are considered one of the sensitive phases for language acquisition. This does not mean that a later start is unsuccessful. Elementary school children still have a remarkably high capacity to learn and can acquire new languages very well with the right support.
What Are Common Challenges in Bilingual Learning and How Can Parents Respond?
Understanding these factors makes it easier to put the most common difficulties of bilingual learning into perspective and address them.
One of the most common challenges is mixing languages. Parents often worry when their child mixes words from both languages in one sentence. As described above, this is not a sign of confusion but a normal part of bilingual language acquisition. Over time, and with enough input in both languages, children separate the systems more and more clearly.
Other typical challenges and helpful responses:
- Smaller vocabulary in one language: children may have a smaller vocabulary in one language than monolingual peers. This is normal. When both languages are counted together, their total vocabulary is often comparable or even larger. Regular reading aloud and conversations in the weaker language help.
- Refusing to speak one language: some children temporarily reject the minority language, especially when it is rarely used at school or among friends. It helps to create positive occasions in which this language feels alive and useful.
- Uncertainty in writing: learning the grammar and spelling of two languages at the same time is demanding. Structured support in class and patient practice at home build this skill step by step.
- Social pressure: children who speak a different language at school than at home can sometimes feel caught between two worlds. Open conversations about multilingualism as a strength help them develop a positive language identity.

How Can Parents and Schools Support Language Development Together?
Support is most effective when home and school work together. Children benefit most when both languages are present in their daily lives consistently, positively, and meaningfully.
For parents, the proven strategy is one person, one language: when each parent consistently speaks their native language with the child, the child learns both languages in authentic situations. Consistency matters more than strictness. The point is not to correct the child when they switch languages but to be a reliable language model yourself.
Practical tips for family life:
- Read aloud regularly in both languages, even when your child can already read alone.
- Make books, films, and music in the minority language part of everyday life.
- Encourage contact with peers who speak the same language.
- Don’t over-correct mistakes; instead, use the correct forms naturally in conversation.
- Value multilingualism as a strength and special ability, and say so.
The school does its part by offering structured lessons in both languages at different levels, identifying learning gaps early, and providing individual support. Close communication between teachers and parents is essential so that progress and challenges are recognized promptly and addressed together.
How Does ISR International School on the Rhine Support Bilingual Learning?
At ISR International School on the Rhine in Neuss, near Düsseldorf, Germany, we help elementary school children every day to acquire two languages confidently and with joy. Our approach combines international educational standards with a deep understanding of how language development really works at this age.
Our ISR Elementary School offers a carefully designed bilingual learning environment tailored to the needs of children growing up with several languages. These features make bilingual learning especially effective at ISR:
- English as the language of instruction, German as a required subject: both languages are a fixed part of daily lessons and are taught at different levels, matched to each child’s individual stage of development.
- Individual language assessment on entry: every new child is carefully placed in the right English and German levels so that lessons match their actual skills from the start.
- Inquiry-based curriculum based on Cambridge standards: our curriculum follows internationally recognized standards and uses methods such as Talk for Writing, which build language skills, reading comprehension, vocabulary, and spoken communication.
- Academic support and peer tutoring: children who need extra help in one language receive targeted support in small groups and, from grade 4, the opportunity to be supported by older students.
- A multilingual school community from more than 60 nations: our international community makes multilingualism a normal part of life and creates an environment in which children experience languages as bridges between cultures.
- Transparent communication with parents: through our ISR app and regular newsletters, we keep parents closely involved so that language development at home and at school go hand in hand.
