A lot of babies will instinctively nurse in their sleep. As an example, if I get home late from work and my "baby" (who is two!) is already asleep, I go ahead and nurse her rather than pumping. She'll nurse without even fully waking up. You could also try ditching the pacifier and the swaddling - that in and of itself will likely make her wake and want to nurse more often. Anyway, watching the monitor constantly and rushing to baby's bed every time the pacifier falls out sounds a lot more nerve-wracking to me than sleeping, waking up when baby does, and nursing baby back to sleep. Even if you don't want to bedshare, would you consider having baby in the same room with you? That way you can hear baby stirring and wake up before she is fully awake, nurse her, and put her back to sleep.
It is way, way, way too early to worry about baby "developing good sleep habits" and "falling asleep on her own." One of the beauties of breastfeeding is that it is by far the easiest way to get a baby to fall asleep and there is absolutely no reason not to use this magic tool to your advantage! As in, get rid of the thought that by nursing baby to sleep, you are setting your child up for not being able to fall asleep on her own at some point. I can assure you that my seven-year-old does not nurse to sleep, although as a baby he always did! (He still likes a bedtime story and cuddles though.) It is perfectly normal for a baby to wake up several times per night and want to nurse back to sleep. If you were a helpless baby and you woke up in the dark alone, wouldn't you want reassurance? Baby gets that with nursing, re-establishes that the most important person in her life is closeby, and also takes care of any hunger or thirst that she may have at the same time.
