Hi, I’m the mum of two bilingual kids and I worked with kids in language awareness for several years. From my experience there are basiccaly two ways to help your daughter: give her the oportunity to discover other languages and culture, being curious, listening to other languages, playing in other languages, meeting people from other cultures and who speak other languages. You can do that very easily anywhere and you don’t need any particular knowledge, only your own curiousity and contact with other languages / culture. Anythng that she enjoys is good. That won’t allow her to speak another language but it can be even more important because she will get used to other languages, other sounds, other pronunciation, other writings, other ways of seeing the world, other ways of expression and that’s the most important part in language learning. You’re building solid foundations that will help her learn any language when she wants. If you understand French you can read these two articles I wrote about this topic and how we can do it in everyday life Eveil aux langues – The French Instinct: le français avec authenticité
The other way is giving her the opportunity to actualy learn one or several languages. But that’s only possible if she lives in a bilingual environment, either at home, at school, in your city, family, etc. To learn a language kids need a lot of real, authentic and useful interactions in that language with family, friends, neighbours, etc. We don’t “teach” a language to kids. They learn it if they need it. If she doesn’t live in a bilingual environment, then you can create one, by looking for a nanny who could speak to her in another language for example, or when she starts going to school by looking for a bilingual school.
But the first option is really usefull. Kids don’t necessarily need to speak other languages when they are very young to become bilingual one day. The sooner is not necesarily the better and even if they are monolingual that doesn’t mean they will struggle in learning other languages. I grew up in a monolingual environment but now I’m bilingual in Spanish and I speak other 3 languages. If she enjoys languages she’ll be able to learn them whenever she wants.
My kids are bilingual because they lived in Spain, their dad is Spanish, at home we speak both French and Spanish everyday. So they learn both languages naturaly. But they also want to learn other languages, because of their parents curiosity. My daughter who is 7 wants to learn Japanese and English, my son who is 9 wants to learn Portuguese. They are always asking us things about other languages. We play games, we meet people from very different places, we listen to music, we read books… in many languages. You’ll see that in my article. The important thing is: do things you enjoy with your daughter and she will naturally be interested in those things.
