Bilingualism does NOT cause speech or language delays—this is one of the most persistent myths in speech-language development. Children's brains are remarkably capable of learning multiple languages simultaneously, and maintaining the home language provides significant cognitive, cultural, academic, and family benefits. If you're raising a bilingual or multilingual child, keep using your home language!
One of the most common questions families ask is whether speaking multiple languages at home might cause or worsen speech and language problems. The answer, supported by decades of research, is clear: Bilingualism does NOT cause speech or language delays.
Bilingual children reach language milestones at similar ages to monolingual children. They babble at the same age, say first words around the same time, and combine words into sentences within the typical range. What may look different is the distribution of vocabulary across two languages—but when you add both languages together, vocabulary is typically comparable to or exceeds monolingual norms.
If a bilingual child has a true language disorder, it will affect BOTH languages—not just one. A child who struggles only in English but is strong in their home language doesn't have a language disorder; they need more English exposure and practice.
Research has identified numerous cognitive, academic, social, and economic benefits of bilingualism. These benefits often persist throughout life.
Children can become bilingual through different pathways, and all are valid ways to develop multilingual abilities.
Bilingual children CAN have language disorders—bilingualism doesn't prevent them, but it doesn't cause them either. The key is accurate assessment that evaluates both languages.
A true language disorder will be evident in BOTH languages. If a child is strong in their home language but struggling in English, they likely just need more English exposure—not speech therapy. However, if difficulties appear in both languages, evaluation and intervention may be warranted.
When children are first exposed to a new language (often at school or daycare), many go through a 'silent period' where they speak very little in the new language. This is normal and not cause for concern.
During the silent period, children are actively listening and learning—they're taking in the language before producing it. This period typically lasts a few months but can be longer for some children. Continue supporting both languages during this time.
Children learn language best from fluent, natural speakers. Always speak your strongest, most comfortable language with your child—this provides the richest language input and supports ALL their language development.
If a professional suggests dropping your home language, get a second opinion. Research clearly shows that maintaining the home language supports (not harms) English development and provides essential cognitive and family benefits.
Mixing languages within sentences or conversations is normal bilingual behavior, not confusion. Code-switching actually requires sophisticated knowledge of both language systems.
A bilingual child may know some words in one language and other words in another. When you add vocabulary from both languages, it typically equals or exceeds monolingual norms. Don't compare only English words to English-only children.
Language is the foundation for communication, learning, and social connection. It includes both understanding others (receptive language) and expressing yourself (expressive language). The first three years of life are the most critical period for language development when the brain is optimally wired to absorb language. Strong language skills are essential for reading, writing, academic success, and building relationships throughout life.

While some late talkers eventually catch up on their own ('late bloomers'), recent research shows that natural catch-up rates are lower than previously thought—only about 6-19% fully catch up without intervention. Early evaluation and intervention provide the best outcomes and should not be delayed.

Every child develops at their own pace—milestones represent ranges, not exact deadlines. Use these benchmarks as a guide, and remember that variation is normal. However, if you have concerns, trust your instincts and seek an evaluation.
