J.,
I too had this problem, except my daughter was 6 months old and would have nothing to do with the bottle. I tried every bottle out there. I had to go to a sales conference (I worked from home and was able to nurse full time). My husband and mother took the week off to watch her and wean her. She didn't eat for a few days (of course I'd nurse her in the morning and at night). Finally, by the end of the week, she took the bottle (Avent). The next week I started nursing her again full time and my husband had to wean her all over again a month later, then I just went full time bottle. Tips for you - make sure you're not the one trying to feed her a bottle, in fact, when someone tries to give her a bottle, you may want to leave the house for a bit. Just keep trying, she'll get it! Good luck!!
