Are you sure? ; )
I realise now that I wasn´t really tuned in to any language other than English with DD 1. Now it seems to have sunk in with me that DD2 is trying to copy our THREE languages, and not just speak to me in English (old fool I am).
So just a thought... multilingual kids may just be very misunderstood... in retrospect DD1 may have been speaking fairly coherently a mixture of languages, when I saw her a late speaker, still babbling ...
Do you have any thoughts on this?
