I feel for you. It's so awsome to hear that my daughter isn't the only boob addict out there-lol! I always tell people that she would be thrilled if I had her lips surgically attached to my breast!
I was experiencing the same exact thing with her but I started to deal with it a bit sooner. I remember feeling like a prisoner, too. My baby was reattatching every hour or two!!! I feel bad for you because you now have the added frustration of dealing with a baby who is in the throws of that typical attatched-to-mommy phase that begins around 9mo.
I would recommend two things. 1)Get the book Secrets of the Baby Whisperer by Tracy Hog and 2)once you come up with a game plan, you can have your daughter sleep in your bed for the first few nights until you get your baby calm (it may take an hour or 2 at first) or it may not be an issue because you'll be in there with them while the baby is screaming. After a while you'll be able to leave when she is just calmly fussing herself to sleep and that shouldn't bother your daughter much.
I can't express enough how patting my daughter on the back or bottom while sssshhh-ing her helped to calm her. The trick is to stop the soothing as soon as she is quiet and then start again only if she begins to cry/fuss again. This teaches her that she needs to sleep on her own but that you are there for her. That way she won't become afraid of her crib.
By the way, I feel the need to touch on another point. You may already know this, this being your second, but I'll point it out just in case. I needed it pointed out to me! Obviously your baby is dependant on suckling to fall asleep. Hard enough for you and baby. But, because your baby is waking up every few hours and latching on for comfort, she isn't learning the skill of being able to fall BACK asleep once she wakes up in the middle of the night. This has huge implications. I found out that when she would wake up, she thought she was up. She didn't understand that because she was still tired and it wasn't time to waken that she could just go back to sleep. My breast wasn't there to reassure her and so now she was stuck awake w/o her normal soothing method. I had to teach her that skill. Unfortunately, I didn't have the book I recommended at the time and used the cry-it-out method with her to establish these good habits. I then realized she was afraid of her crib and didn't want to be put down. That was when I turned to Tracy Hog.
I, too, have a stong-willed and quite spirited little girl and I have learned that because of her particular temprament, if I allow her to fall asleep at the boob AND STAY THERE twice in a row we have to go back through the process again with it taking longer to comfort her to sleep when I put her back in the crib. So just know that that is a reality with children like ours--give them an inch...!
WARNING: I would not use music or binkies or anything with babies like ours. When they awaken in the night or during a nap, they need to recreate the same atmosphere they fell asleep with. If that included music or a now out of reach binkie, that ain't gonna happen! They must learn to fall asleep w/o any props.
I, too, loved the romantic idea of attatchment parenting but after a while I realized that not ALL aspects of it were going to be compatable or realistic. If it's not working, change it. Don't feel bad. I hope this ends up helping. God bless you!!! I'd love to know how it went...
