We were in a similar situation with DS6 last year in Kindergarten. Unfortunately, his teacher refused to meet with me and referred me to the Principal, who also refused to meet with me (she said, specifically, "There's no reason for a meeting, we have nothing to discuss because we aren't doing anything differently"). So, I would say that just the fact that she's actively pursuing a face to face meeting is a great sign that things aren't too far gone and she really wants to find a way to make it work.

Good luck!
