Hi A.
Everyone seems to think crying it out is the best thing to do. I, for one, can't let my baby cry for too long at all...I feel like I'm abondoning him! I'm still nursing Daniel and he does still wake up to nurse, but it took a while to get him in his crib...Try What we did: put an unwashed heavy towel that you used that way it smells like you and it imitates the weight of your comforter, blanket,etc on her body...when you put her to bed initially, make sure she's not asleep...very drowsy is a good stage...If she wakes up, rock her to that stage again and do it again...it took several nights and nap times of this to get daniel to sleep, it was hard and tedious, but at least he wasn't screaming his poor little lungs out and mommy was there with him... making sure she's not asleep when you put her down is crucial b/c that's when she's learning to self-soothe. babies usually wake up during the night anyway, but when they're sleep trained they just go right back to sleep...(I remember my daughter "talking" to herself some nights like at 2-3 am!)
Blessings!
