Hi N.
You may want to try to address one transition at a time... either weaning from nighttime nursing first or the bed. It would likely be easier for you to night wean her, then once she is accustomed to getting through the night without nursing, begin the transition to the crib. My daughter was two when I night weaned her. It took about a week. Each night got easier, though. My husband was very helpful. He would hold her and rock her or I would pat her back and reassure her. I would show her that it was dark outside and tell her that we would nurse when the sun was up. Shortly after that, I became pregnant with my son, so our daughter moved out of our bed into her own. That was a longer transition, because we really didn't mind her in our bed. She still ends up there most nights anyhow. The Dr. Sears web site www.askdrsears.com has some great suggestions for both weaning and transitioning from co-sleeping. Best of luck to you!
