I don't know the details of any studies, but I think the general consensus these days is that bringing up children multilingual from the start is a positive thing to do, even if it can slightly delay their initial development.
As our oldest is starting to learn to read at school, I wondered if anyone knows if there are any studies about learning to read in two languages? Specifically: is there a difference in the conclusions for reading compared to talking?
(The two languages in this case are French & English).
