DH speaks English exclusively to DS9mo. I speak mostly English to DS. When I speak my native language to DS, he always laughs hysterically. My parents, who watch him during the day, speak our native language to DS. He doesn't seem to have an issue with the two different languages.

I really want DS to be able to read and write in my native language, but I am afraid of the amount of work that would involve.

Do your kids know how to read and write in other non-Latin-based languages?
