I never knew before I was a mom how tough this sleeps stuff is, you know?! I feel you...at 5.5 months my dd was still up multiple times a night and I thought I was literally going to keel over from exhaustion. But, fast forward another 7 months and she is an awesome sleeper and I can't even remember the last time I went in there during the night. I don't think I have a magic answer for you, but a few suggestions. One, which is kind of a sucky one at this point, is patience. When my dd finally slept through the night, she never looked back-I strongly believe that they just do this when they're ready, not when we "make" them. We didn't do CIO-knowing what I do about child development, I don't think that it does our kids any favors in terms of trust, communication, relationships, etc. to not respond when they cry, being that it's the only way they can communicate. But, what we did do starting at around 7 months was start stretching out the times between feedings. So, if she wants to eat after 4 hours of sleep, for example, then set a time span like 6 hours, and until then, either you or your significant other go in there and do whatever you need to to comfort her, other than feeding her. Then, once she is going 6 hours, stretch it to 7 (with comforting), then 8, etc. Sometimes it took singing, holding, rocking, a bottle of water, etc, but I was determined to stretch out those feedings! Eventually, when she was older (more like 9 months) if she would cry during the night we would not pick her up, but would stand by her and rub her back until she fell back asleep. It got to the point where we would just walk through her door and she'd just flop back down onto her tummy, because she knew the drill :). One other suggestion-about the pacifier thing-I don't think you're supposed to have any kind of pacifier strap in the crib. What you could use, though, is one of these small animals with a pacifier-they're easier to grab onto for little hands. http://www.amazon.com/Wubbanub-Infant-Plush-Pacifier-Gree...
I don't think you can use this, though, until she's done with the swaddle.....have you considered a Halo sleep sack? That's what we moved to after swaddling and still at 13 months she sometimes sleeps in it.
I hope a little of this is helpful. Good luck!
