I just posted a great response (actually, when you read the abbreviated version below, you'll know that I'm just guessing) but it seems to have vanished.

My suggestion is this: see if you can't find some 'physical' activities that he enjoys (I mean, where you don't 'have' to talk: blocks, legos, cars, trains) and play with him, speaking only English. I guess that, if I were doing this, I'd try to translate everything he says with gestures into English.

I don't know, though, I'm just saying what I would do if I had the job. Let us know what you DO do and how it works out, though. I'd be interested in hearing it.
