How would they now? By no means those dual nationalities are centrally managed. And therw is no obligation to state a second cotizenship on any papers. Disclaimer: Dual citizenship kids in Europe.

You're probably right re: citizenship but this is about language, how could one "hide" being bilingual, especially if we're talking about a young child?
(Even in kindergarten all my daughter's friends are 100% aware that she and I speak a language when we're communicating solely with each other that isn't the language my daughter uses the rest of the time in kindergarten.)
Being bilingual is impossible to hide, that's true. My son had intensified German lessons as well, being bilingual with German as one of those. He was not amused, it was free private German lessons so us as parents didn't complain.
