My 4 month old daughter is currently brought up trilingually the OPOL way, I speak German with her, my husband Turkish, and she will learn English in the full time nursery she attends and when we are together with friends. We do not keep it clean as DH and I often communicate in English together. So she is growing up trinlingually so far.
Now the complication
- my husband is actually bilingual and speaks native Russian as well, so far he hasn't mixed it in, which means DD most likely will never learn it. If he did mix it in, she could learn a bit of both his languages, maybe get confused, but with these two languages we'd be fine if she only gets to a conversational level, as she will never do schooling in them, so we are wondering if it is worth it just to add another language?
- the only outstanding state school in our area is bilingual English/French. So our option is either pay for private school, or send her to the bilingual track of a state school, which would mean half her schooling would be in French.
I speak 3 languages fluently as almost everyone in my family and my husband speaks 5 languages fluently, my grandmother even speaks 9 languages and used to be an interpreter, so I assume my DD should have an above average talent for languages.
So I think it would be great if she could grow up with 5 languages, at least she would have a perfect accent at all, even though she might only be native standard in two or three of them.
My only worry here is if it will negatively impact her performance at school, for example if her English will be worse like this than if she went to a pure English school, and obviously if her performance in the French subjects of the bilingual school will be below what it could be if she went to an English school. On the other hand, I think in the long run it is more beneficial to be fluent in five languages than to have good primary school grades, and maybe it doesn't even make a difference.
I know popular opinion is that this could be too much (esp DH mixing two languages), but I wonder if there is any solid research done one this (AussieCelt, I am counting on you!!). What is the evidence? Surely, if my husband could learn five languages (his two native languages plus three learning in adolescence), it should be even easier to learn five from birth?
Interested to hear what people think about the third home language as well as bilingual schooling. thanks!
