Well, chances are if she's hungry, she's not really going to be napping anyway. Do you have a "deadline" that you need to get her to take the bottle by? Or are you just looking to be able to have a break from her here and there? I ask b/c I got my dd1 to take the bottle when she was about 4 mo by offering it before each feed -- if she refused (which she did consistently at first) I would just nurse. After about 2 weeks of this, she took the bottle fine and had no trouble again. It was a lot less stressful for me than not feeding her at all. HTH!
