English only! My son gets Japanese from hoikuen and will always have lots of exposure to it living here, so I want to make sure that I only speak English with him and that he associates English with me.
My husband and I only ever spoke Japanese to each other before baby came along (husband can speak English though), so I have to admit that switching to mostly using English at home has been a bit of a struggle! There are just so many words and phrases that come naturally in Japanese, and I find myself need to make an effort to express these in English, even though it’s my native language! But I know I have to stick with it, and have been.
But like others here, my son is still young, so we still have a long ways to go 🙂
