i would do some serious research before deciding about crying it out...the stress levels it produces in babies are pretty scary, and the body's natural opiates are released in response to all that stress, which is why babies finally quiet...not because they're "learning" how to be on their own.
it comes down to basic biology. In a hunter-gatherer society, babies would sleep with their M.. Being separated would be a big problem for a baby. We come from that model, 100,000 generations of our history. We have only 100 generations of being this industrialized society that separates babies and trains them. We fight basic biology when we try to force it. It might be something we think we need, but it is a lot of work, and it doesn't even make it easier on us--that's the crazy part.
So my advice is just let her lead you. if she's hungry, feed her. If she needs comfort, comfort her. If she wants to be close to you, hold her. All this control we try to exercise--what is it really teaching? That she doesn't have a voice, that when she tries to tell you her needs she doesn't get heard? I am a big proponent of sleeping with your baby, and I can tell you that after three kids, we have no sleep issues, no behavior issues, no problems--just three very confident, easy, pleasant kids. I'm not a hippy, I'm a well-off suburban M. who was lucky enough to have someone be frank with me early on. And it was easier getting them out of the bed when they were older.
If this isn't going to work for you, just be there for her when she needs you. But you'll get a lot more sleep if she's with you. Having a baby shouldn't be this hard. I would just let it be easy.
