Will Learning Two Languages Delay My Child's Speech?

If you are raising your child with two languages and you have noticed they are not talking as much as you expected, it is natural to wonder if the two languages are the problem. So many parents in NYC ask this quietly, worried they have somehow made things harder for their child. Take a breath. You have not done anything wrong, and the science here is genuinely reassuring.

Two languages do not cause speech delays

This is one of the most well-established points in child development: growing up with two languages does not cause a speech or language delay. It does not “confuse” your child’s brain. Children all over the world, and all over New York City, grow up hearing Spanish, Yiddish, Russian, Chinese, Bengali, and English at the same time and learn to speak all of them.

Your child’s brain is fully capable of sorting out two languages. Bilingualism is a gift, not a burden.

What is completely normal

When you are listening closely, some things can feel worrying even though they are typical for bilingual kids:

• Mixing languages in one sentence. This is called code-mixing, and it is normal and healthy. It means your child is drawing on everything they know.
• Knowing fewer words in each language on its own. A bilingual toddler might know 30 words in Spanish and 30 in English. Counted separately, each looks small. Counted together, their total is right on track.
• Leaning on one language more at times. Depending on who they are with and what they are doing, one language may come out stronger for a while. This shifts over time.

The key idea: always count both languages together. When you do, most bilingual children have a total vocabulary similar to their peers.

The myths worth letting go of

• “Two languages will overwhelm my child.” They will not. Children are built for this.
• “I should pick one language so they don’t fall behind.” Dropping your home language does not speed up speech, and it can cost your child a rich connection to family and culture.
• “Mixing words means something is wrong.” It does not. It is a normal stage.

The signs that DO warrant a closer look

Bilingualism does not cause delays, but delays can still happen in any child, in any language. What matters is whether you see a pattern across both languages, not just one. Consider an evaluation if you notice:

• Very few or no words by around 18 months, in either language
• Not putting two words together by age 2 (in any combination of languages)
• Trouble understanding simple requests in the languages they hear most
• Losing words or skills they used to have
• Little interest in communicating through sounds, gestures, or pointing

A true delay shows up no matter which language you listen in. If your child is chatty in one language and quiet in another, that is usually just exposure, not a delay.

How an evaluation handles two languages

A good developmental evaluation looks at all of your child’s languages, not just English. In New York, Early Intervention is a state program for children from birth to age 3, and it is free to families. You do not need a doctor’s referral or a diagnosis to start, and you do not need Medicaid. Private insurance does not disqualify you either.

You, or anyone, can make a referral to Star EIP or by calling 311. It goes to the NYC Early Intervention Program, which assigns an approved agency like ours. We schedule a free developmental evaluation, usually right in your home, in the language that works for your family where available. If your child is eligible, you and the team build a plan together and services begin.

You are giving your child something valuable

Two languages open doors, deepen family bonds, and grow with your child for a lifetime. Keep speaking, singing, and reading in every language you love.

If you are still wondering whether your child’s speech is on track, the kindest next step is simply to check. A developmental evaluation is always free.
