Why is it so difficult for you to accept that your husband wants to share what he knows about his own culture with your child? What’s at the root of your discomfort with raising a multilingual child? What’s stopping you from teaching your child English and French while your husband teaches him a Creole dialect? What’s driving this (erroneous) preoccupation you have with “real” and “official” language?

The answer is racism.

Also, there’s absolutely no reason why child can’t learn English, Creole, and French—everybody wins, especially trilingual child.
