DD is bilingual. It's possible that we'll move to another country some day, and I'm worried she may end up forgetting one of her first languages.
One of her languages is English, so I'm not worried about her losing that, but the other language is rare and not spoken anywhere but where we live now. Of course we'd do what we could to keep it up, but I'm not perfectly fluent in it, and I'm not sure whether just DH speaking it would be enough.
I have two close friends who migrated & switched languages at 5 and 7 years old, and neither of them speak a word of their first languages. :/
Does anyone have any experience with this? From what age is a child unlikely to forget their native language if it's no longer spoken around them?
