Not my parents, but as a parent my wife and I have different native languages. I speak to my son in English, the only language I know. My wife talks to him in Indonesian unless it’s a conversation involving me then it’s English.
My son will answer her in English even though he can speak and understand Indonesian. Although his Indonesian accent is becoming more influenced by English as he gets older, probably due to the lack of using the language. Calls with his grandmother help as she doesn’t speak English but she’s partially deaf which doesn’t help.
