DH is from country X, I am English and we live in England. DH’s family only speak their language, my family only speak English. I speak X language but not perfectly fluently. We want to move back to X, but it won’t be for ten years or more.
How can we raise our child to be bilingual so they can communicate with their paternal family integrate when we move back? I don’t know anyone who’s done it successfully, and we can’t send our child to an X language school as they’re only in London, or boarding schools.
