# How do bilingual children usually develop language?

Bilingual children develop language on broadly the same timeline as monolingual children when you count both languages together. Mixing languages and a brief silent period are normal. A true difficulty shows across both languages — and bilingualism is never a reason to delay seeking advice.

*Two languages do not confuse a child — a growing brain is built to hold them both.*

## In short
Bilingual children develop language on broadly the **same timeline** as children learning one language. They babble, say first words, and start combining words within the typical age ranges. Their **total** vocabulary — across both languages combined — is what counts, even if the count in any single language looks smaller for a while. Hearing two languages from birth does **not** cause delay, and learning a second language does not "take away" from the first.

## What this usually looks like
- **Babbling and first words** arrive in the typical windows — first words around 12 months, two-word phrases by around 24 months — when you count *both* languages together.
- **Mixing languages in one sentence** ("code-switching") is normal and a sign of skill, not muddle — it follows real grammatical rules.
- **A quiet "silent period"** can happen when a child is newly exposed to a second language (for example starting school), as they listen and absorb before they speak.
- **One language may seem stronger** than the other depending on where and with whom it is used — this naturally shifts over time.

What matters is the **quality and amount** of real, warm interaction in each language — talking, reading, singing, naming things together — far more than which languages they are.

## When to seek a developmental check
Bilingualism is *not* a reason to delay seeking advice. The signs worth a check are the same as for any child: no babble or gesture by 12 months, no single words by 16 months, no two-word phrases by 24 months, or any **loss** of words or skills. A genuine language difficulty shows up **across both languages**, not just one — so it is always worth describing your child's skills in every language they hear.

## The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an online form. If you are ever unsure, a clinician can map your child's whole-language profile across every language they speak, so support fits your family's real life.
