For us a gradual approach to helping our daughter learn to fall asleep was best -- I just couldn't do cry it out. I would time how long you usually rock her to sleep and then start rocking her for shorter and shorter times. We would listen to some music and at first I rocked her for three songs, then a week later I rocked her for only two songs, the next week one song. Each night when the final song of the night started I would tell her, "at the end of this song I'm going to put you in your crib." Once I put her in her crib I would lay down next to her crib and sometimes sing until she was quiet. Finally I was just rocking her for a minute or two, putting her in her crib completely awake and able to leave the room almost immediately after -- it took a few months to work up to this level, but for me it was worth it because we never had to do cry it out. Good luck.
