The Most Common Myth — and the Truth Behind It

The most common misconception our ECI team hears is that learning two languages at the same time will delay a child’s speech development. Families worry that exposing their child to both English and Spanish is the reason their child isn’t talking as much — or as clearly — as other children their age.

The reality is more nuanced — and more encouraging. When speech-language pathologists evaluate a bilingual child’s vocabulary, they count words from both languages. A child who says “dog” in English and “perro” in Spanish has two words, not one. And when you look at total vocabulary across both languages, bilingual children are often right on track with — or ahead of — their monolingual peers.

A true speech or language delay looks the same in bilingual and monolingual children alike. If a child is struggling with language development, it would be present regardless of how many languages they hear at home. Bilingualism is not the cause, and eliminating Spanish from your home is not the solution.

How Bilingual Development Looks Different and Why That’s Okay

Bilingual development doesn’t follow the exact same path as monolingual development — and understanding those differences can help caregivers recognize what’s typical and when to seek support.

Spanish words tend to have more syllables and more complex pronunciation than many English words — think of rolling r’s and multi-syllable words that young children are still learning to form. As a result, you may notice a bilingual child using approximations (simplified versions of words) more frequently, or reaching full words a little later. This is normal.

There are also some notable advantages. Research shows that bilingual children often demonstrate stronger working memory than monolingual children. They may also show better executive functioning — the ability to focus attention, shift between tasks, and manage daily routines — because their brains are constantly navigating two language systems.

Signs that may warrant a closer look include:

• Limited vocabulary in both languages (not just one)
• Difficulty being understood by familiar caregivers
• Not combining words by 24 months in either language
• Frustration or withdrawal during communication

If you’re seeing these signs, an evaluation — not a change in home language — is the right next step.

Code-Switching Is Not Confusion — It’s a Cognitive Strength

Code-switching — moving between English and Spanish within a single conversation or sentence — is one of the behaviors that most concerns bilingual families. When a child says something like “I want the pelota,” parents often worry it means their child is confused about which language is which.

In fact, code-switching is natural, culturally accepted, and happens across bilingual communities around the world. Children (and adults) code-switch to fill vocabulary gaps, emphasize a point, or because a word in one language is simply more available in the moment. Importantly, bilinguals who code-switch are not breaking the rules of grammar in either language — their brains are managing both systems simultaneously.

For many families, code-switching is also a way to connect with culture and community. It’s a marker of belonging, not a barrier to language development. Our specialists describe it as a sign of high cognitive skill — evidence that a child’s brain is working hard across two rich language systems.

Supporting Both Languages with Confidence

One of the most common questions bilingual families bring to Brighton Center is whether they should focus on one language at home to help their child catch up. It’s a fair question — and the answer, backed by research, is reassuring.

Birth to age five is the most critical window for language acquisition — a time when children’s brains are uniquely wired to absorb language naturally and effortlessly. If a family wants their child to grow up bilingual, there is no better time than right now to expose them to both languages. Waiting or withdrawing Spanish during this period means missing the window when learning is most natural.

Our Early Childhood Intervention (ECI) team encourages families to hold on to both languages with confidence. If you’re receiving mixed messages, our specialists can help you understand what the evidence actually shows and what’s right for your child.

Why Heritage Language Is More Than Just Communication

Language is never just about words. For bilingual families, Spanish is often the language of grandparents, of family stories, of cultural traditions and belonging. When children grow up with access to their heritage language, they gain more than communication skills — they gain a connection to who they are and where they come from.

Our ECI specialists emphasize that early exposure to Spanish builds the confidence children need to continue using the language as they grow. Children who are supported in their heritage language from an early age are more likely to maintain it through school and into adulthood — and all the relationships and opportunities that come with it.

What a Bilingual Speech Evaluation Looks Like

If you’re wondering whether your child might benefit from a speech evaluation, knowing what to expect can make the process feel much less daunting.

At Brighton Center, a speech-language pathologist evaluates bilingual children by assessing both languages — not just English. The evaluation typically includes a parent interview about language history and daily communication, play-based observation of how the child interacts and communicates, and standardized assessments when appropriate. Families should be prepared to share details about which language the child hears most at home, how they communicate with different family members, and any other developmental milestones that feel relevant.

This whole-picture approach matters. When only one language is assessed, bilingual children can appear to have delays they don’t actually have — or real delays can be missed because they’re attributed to bilingualism. Our specialists are trained to tell the difference.

If therapy is recommended, the plan is tailored to the child’s unique linguistic background — supporting both languages, not replacing one with the other.

Simple Strategies to Nurture Both Languages at Home

You don’t need special materials or formal lessons to support your child’s bilingual development. Some of the most effective strategies happen naturally during everyday routines.

Narrate and label in both languages. As you move through daily routines, name what you’re doing in one language, then the other. Going outside? Try: “Let’s go outside” followed by “Vamos afuera.” Putting on shoes, eating lunch, giving a bath — these everyday moments are powerful language-learning opportunities.

Keep the languages separate within sentences. Rather than mixing languages mid-sentence (e.g., “dame la ball”), try completing thoughts in one language before switching: “give me the ball” and then “dame la pelota.” This approach helps children build complete patterns in each language.

Read in both languages. Books are one of the richest sources of vocabulary and sentence structure. Reading in both English and Spanish — even the same book twice in different languages — exposes children to a wider range of words and reinforces both language systems.

One Family’s Story

One mother came to Brighton Center after months of hoping her son would catch up on his own. She had been doing everything she could to support his development at home, but when he turned two and his vocabulary hadn’t grown the way she expected, she decided it was time to reach out.

The evaluation revealed a level of delay that surprised her. But our team reassured her: it was not too late, and she had done nothing wrong. Within the first few months of services, her son’s vocabulary began to grow. By the time he graduated from the program, he was speaking in full sentences and no longer needed therapy.

On graduation day, she was in tears — grateful to her ECI team not only for helping her son reach his milestones, but for teaching her how to better support his development at home. Her message to other families: don’t wait as long as she did. Reaching out early is an act of love, not an admission of failure.
