Raising a Bilingual Baby: Milestones & Myths | Parenting Hub
Bilingual babies do not have language delays. Here's how to support more than one language and what's normal at each stage.
Babies are wired to learn more than one language from birth. The evidence is clear: bilingualism doesn't cause delay, and the cognitive benefits last a lifetime.
What the research shows
Bilingual babies hit language milestones (babbling, first words, two-word phrases) at the same time as monolingual babies. Their vocabulary in each language may be smaller, but the total vocabulary across languages matches or exceeds monolingual peers.
How to support more than one language
- Speak the language you're most fluent in — quality beats quantity
- 'One parent, one language' is one option; 'one place, one language' (home vs daycare) is another — both work
- Read, sing and play in each language
- Welcome 'code switching' (mixing languages in one sentence) — it's a sign of skill, not confusion
- Don't drop the heritage language if your child starts daycare in English — you can't reintroduce it as easily later
When to see a doctor
Bilingualism is not a cause of language delay. If your bilingual child doesn't hit the same receptive and expressive milestones as monolingual peers, see your GP or MCH nurse — they need the same assessment any child would. Always include a hearing check.
When to seek help
- No babbling by 9 months
- No first words by 18 months (in any language)
- Loss of language skills
- No 2-word phrases by age 2.5
Common questions
Will my child mix up the languages?
Yes — and that's normal and clever. Bilingual children learn to keep languages separate by 3–4 years, and code switching is a sign of fluency, not confusion.
