Really? Can kids with Language Impairment or _____ Learn TWO Languages?

Is the earth round, really? It seems flat to me. I’ve been in many places in the world and I haven’t heard about anyone falling off it and so from my own logic and experience it appears the earth is flat. This is how evidence goes it seems and I find myself getting frustrated but I do try to understand the logic of disbelief– even in light of evidence. Yes, the earth is round (a sphere actually) and children with language impairment and those with other disabilities that affect language learning CAN (and do) become bilingual. No, they do not become MORE delayed.
