I am curious, if you are practising OPOL at home and if your children are taught in another language at school, what language do the siblings speak to one another in?
I'm curious because our home is OPOL EN/DE, our DD goes to a school where she is taught in another language, DS has just arrived and, when he is old enough, he will attend the same school as DS. I was wondering what language DD and DS will speak to one another in. I can always wait and find out but just wondered if there is anyone out there with any experience of this?
