There are alternatives to crying it out, which would tear my heart out to listen to, personally. Like another poster said, take it slow. Baby steps. If you can get the crib in your room great. I don't think it would be easy to get her to sleep in a room alone just yet.

Also, she's not even two, she's still a baby. She is still dependent upon you to fulfill her needs. Independence comes with age naturally.
Plus, her brain is still developing and will do so until she is at least 24 months. The first two years are critical. This is why the World Health Organization recommends breastfeeding for at least the first two years. If you can stick it out a little longer, then it would be beneficial to your daughter.
