Tee hee, I was lopsided for a good few months, SJ! LOL, it is funny, but they do even out again.
Don't know about your bottle dilemma, sorry. But it sounds like she has a great apetite and is doing really well at demanding her feeds, so I would be surprised if you found it hard to get rid of the bottle once your nipple's all better, KWIM?
The unsettled thing could just be that she's a little baby and sometimes they are just cranky. She's still so little and everything is very new and different and stimulating to her. The comfort of your breast would be very appealing to her. Keep up the fantastic work, mate!
