An American friend recently asked me a difficult question: How do you bring up a bilingual child?
She and her Japanese husband now have a 2-year-old son, and they are keen for him ultimately to be fluent in Japanese and English.
Having brought up four children who are bilingual in English and Japanese, while living for decades in Japan with my British wife (it's harder, I can tell you, when neither parent is Japanese), I have been around the block on this and, moreover, I've paid my dues. In fact, it's not only metaphorical dues that I've paid; for you will soon see that bilingualism doesn't come cheap.
