Cultural clash between parents at home

Hi Sara, I am a first generation Canadian Born Chinese and my wife had immigrated to Canada and has Canadian Citizenship. We both live in Vancouver, BC and have two kids.My first child is about to start Kindergarten and my second child is still in preschool. I want my kids to speak more English at home so that they can do better in school but my wife disagrees and wants them to speak more Chinese at home.From my past experience, when I was elementary school, I had problems with English grammar. My teachers said to my parents that I should speak more English at home to improve my English skills to do well in school and since then my parents have been speaking English at home.My wife is accusing me of killing our cultural identity saying that I'm teaching our kids to forget their mother tongue. Now I'm in a flood basement scenario, help!
