we follow attachment parenting also. Our children are know 4 and 1/2 and 3. It was alot easier when they were younger it has gotten harder as they have gotten older. The cry it out was not for us. I tried one time and cried the whole time i did it. My husband even held me down ebcuase i wanted to go and get my daughter to stop her crying and he found out just how strong i was. LOL. It was horrible so we made the point only to do what we are comfortable doing. Now both our kids still end up in our bed and refuse to sleep in thier rooms but since they have moved out of the cribs we kept the crib mattresses and have them on our bedroom floor where they start sleep at. Now by morning they are in our bed but if we notice that we wake them up and tell them to go back to thier mat. and they fight but do it.
As for suggestions, have you tried instead of taking her out and holding her until she falls back asleep leaving her in her bed and standing there or sitting with her holding her hand. Then maybe each day moving closer to the door until you are not in her room at all. That way you ease her into comforting herself at night./ We did this with our daughter and it worked until one night she ended up our bed.
