We have a 1.5 year old boy in an English-only household. We'd like him to learn Chinese (Putonghua / Mandarin) over the next ten years or more. What are some of the best ways to get him exposed to the language (and at what rough ages should we start that exposure)?
Bear in mind at this stage he is developing quickly his understanding of English and starting to speak basic English words. So we don't want to confuse his English learning and development but want to offer him the best opportunities to learn Chinese at the appropriate stages.
