Im English. DH is French. We are both fluent in both languages.
We are currently doing a rough OPOL with our toddler. But I was wondering - how will it work later when DS is telling us both something at the same time? (Eg about his school day). Is it just that we only reply in our native languages and DS talks to us in whatever language...or shoul he tell us his story in both languages (which will feel artificial as we're both fluent)
