DH and I are Spanish and live in the US; so we pretty much expect our baby (coming in September!) will be bilingual. Our plan is to exclusively speak Spanish at home, and when the baby is older to spend time regularly in Spain with family in order to be truly bilingual, even if that means that we won't really be able to go on vacation to other countries.
We're also somewhat prepared for the fact that we might have to deal with teaching our kid to read and write in Spanish, though we don't really know how we'd go about it.
Since we live in the US, we're not really worried about English.
Our long term plan is at some point in the next 5-15 years to go back to Europe. Spain would be ideal, but not a must. This is why it's important that our kid be truly bilingual including reading and writing.
Thing is, I would really like my child to be better at languages than either of us is; and I feel that trilingual is what we should really be aiming for, but I'm not sure how to make it work or what language to choose as third language.
My first question would be when to introduce the third language - nanny, day care, preschool, school?
Our plan at this point is to have a full time nanny once we have to go back to work until the kid is 1.5 - 2 years, then day care or directly preschool. I know there are a few language immersion preschools in our area (though I haven't really done much research on this yet) - Spanish and Chinese seem to be options here, though I suspect French, German, and Japanese might also be available though I'm not entirely sure. Also not sure if looking for a nanny who would talk in either Spanish or whatever we choose as L3 is important / desireable - since we both work full time, I assume the nanny would in practice spend more waking ours during the week with our child than either of us ().
My second question is - if you were choosing a third language, how would you choose? I feel like Chinese (Mandarin) or Japanese would be more useful long term, but I can't help but wonder if they would really be that useful if the child never had the opportunity to spend a significant amount of time in either country, and / or the education in that language had to be discontinued at some point (what if I find a Japanese immersion preschool but not school? What if we move to somewhere in Europe where these languages are not available in an immersion setting?). French or German feel safer as a long term investment but way less useful.
Any ideas or opinions?
