Secret to raising a bilingual and biliterate child in Chinese and English: spousal support
No, not the type of spousal support divorcees talk about. I am talking about a cooperative and supportive spouse. It really matters whom you marry, just like everything else. FB COO Sherry Sandberg said so, in another context of course, as in “Lean In”.
Either the spouse has a good income, so that you can hire Chinese tutors or household help, and/or let you stay home to teach the kids Chinese, s/he does the bulk of the house chores (so that you can spend time to teach Chinese and establish a CLE), or the spouse does the teaching/CLE part. It is very time consuming to teach Chinese well and takes the cooperation of the entire family. It would be even better than the grandparents can chip in too.
