My son (who was also exclusively breastfed) refused at 11 months...I was perfectly fine with it, I wanted to stop at a year anyway, and he took charge. I pumped for a month (which I would not do again, it is a pain, but he was the first) although the ped. said 11 months was fine to switch to milk...so, unless you are upset by it (which you don't seem to be, seeing as you were planning on stopping soon anyway) I would be happy that she did it on her own time.
