not sure how to phrase this so it makes sense.
you know how some people find languages easy, so you could be brought up speaking one language but you naturally find it easy to learn more languages and equally some people struggle and really can't learn another language.
I am curious if children who are being raise bilingual can also struggle. So some naturally just learn both and are fine but is it actually a kind of 'programming the brain' issue and some people genuinely CAN'T learn more than one language without problems and therefore could affect a child who is trying to learn both as native languages?
does that make sense? purely out of curiosity. I know a child who is being raised bilingual (now 6) and who struggles with both languages, I don't mean just reading and writing but more general confusion, she just struggles with both so it made me wonder if some of us are just wired up to only deal with one language.
