Language Mixing in Bilingual Kids: What It Means and How to Navigate It
"Bilingualism is not a state of confusion, but a superpower in disguise!"
As a speech and language pathologist, a trilingual myself, and a parent raising multilingual children, I often hear concerns from parents about language mixing. Parents sometimes worry that their child switching between two languages within the same sentence—what we call code-mixing —is a sign of confusion or a language delay. But guess what? Research says otherwise!
Let’s break it down: What is language mixing , why does it happen, and what can you do to support your child's bilingual development?
What Is Language Mixing?
Language mixing, or code-mixing, occurs when bilingual speakers alternate between two languages in the same conversation, sentence, or even phrase. For example, a child might say:
"I want to jouer avec mon ami." (I want to play with my friend.)
This behavior is completely natural and expected in bilingual children—especially those under the age of four. According to Dr. François Grosjean, an expert in bilingualism, language mixing does not indicate confusion ; rather, it reflects linguistic flexibility and a developing vocabulary. In fact, research shows that bilingual children are strategically using the words they know in either language to communicate effectively.
Why Do Kids Mix Languages?
There are several reasons why bilingual children mix languages:
Vocabulary Gaps: Young bilinguals may have a strong grasp of a term in one language but not in the other, so they borrow the word they know best.
Modeling What They Hear: If adults around them mix languages, children will naturally do the same. This is common in multilingual households.
Developing Grammar Systems: Learning two sets of grammar rules takes time! Kids sometimes mix because they are still figuring out how to structure sentences in both languages.
Context & Emotion: Some words carry cultural or emotional weight depending on the language. For example, certain feelings might be better expressed in one language over another.
Cognitive Flexibility: Studies show that bilingual kids can switch between different cognitive tasks more easily than monolinguals —language mixing might just be an early sign of this skill!
Is Language Mixing a Problem?
Not at all! Code-mixing is a normal part of bilingual speech development. However, if a child consistently struggles to express themselves in either language beyond the expected age range or shows difficulty understanding and producing complete sentences in one or both languages, you may want to consult a speech and language pathologist for an evaluation.

How Can Parents Support Bilingual Development?
1. Respect & Normalize Mixing
Instead of discouraging language mixing, show your child that it's normal and even smart! You can respond by repeating their sentence in a structured way.
Example:
Child: "I want to jouer avec mon ami."
You: "Oh! You want to play with your friend? That sounds fun!"
This lets your child know you understood while also providing a complete language model.
2. Boost Vocabulary in Both Languages
Children code-mix less when they have a strong vocabulary in both languages. You can support their development by:
Reading books in each language separately
Playing games that introduce new words in both languages
Singing songs in both languages
Encouraging social interactions in both languages with friends and family
3. Keep Each Language Balanced
A common concern in bilingual homes is that one language may take over. Try implementing these strategies:
One Parent, One Language (OPOL): Each parent speaks a different language consistently.
Time & Place Strategy: Assign specific times or locations for each language (e.g., French at school, Arabic at home) - more about this strategy soon 😉
Contextual Exposure: Use media (TV, music, books) in different languages to reinforce learning.
4. Be a Confident Language Model
The best way to foster bilingualism? Use your own native language(s) confidently with your child! When your child sees you valuing both languages, they'll feel comfortable using them, too.
Final Thoughts
Language mixing is NOT a sign of confusion—it's a sign of bilingual growth ! Instead of worrying, let’s embrace our children's bilingual journey and give them the tools and opportunities to thrive in both languages.
*Remember: Bilingual children are not “two monolinguals in one.” They are uniquely wired to adapt and thrive in multilingual environments. Keep the journey fun, rich, and supportive, and watch your little linguist flourish!
