R.M.
Does she still nurse just fine, and only won't take the bottles? Or is she refusing both?
If she is refusing both, it might just be a "nursing strike" that includes the bottles too. My son went through periods where he didn't want to eat for a few days. They are frustrating and nerve wracking, but if you just keep offering, they pass.
If she is nursing but no bottle, try doing the switch. Start her on the breast then switch to a bottle part way through. Sometimes that works to get babies to take a bottle who haven't been introduced before and are refusing it.
Good luck, I wish I had more advice.
