Hi there
Gosh, you are having a rough time aren't you. OK, I've got some suggestions for you.
The first thing I want to address is the previous occasions when you have tried CIO (Ferber method) with your DD. Have you read Tracy's books, The Secrets of the Baby Whisperer or Baby Whisperer solves all your problems? If you have, you will know that Tracy does not recommend CIO or CC because she believes that it breaks the bonds of trust between the parent and the child. So, because you have tried CIO, you will need to work with your DD to rebuild the trust. Tracy details in her books the process that a parent would need to take to start rebuilding that trust and I would recommend that you have a look at the books and read through those sections.
Basically though you would need to spend time with your DD while she falls asleep, and perhaps spend a few nights in her room with her, while she learns that you are there for her and will respond to her if she needs you during the night.
The other things that stand out to me are the fact that you are rocking/holding your DD to sleep for naps and at the beginning of the night. What is happening is your DD comes into a light sleep phase and is confused because while you were there last time she "looked", now you are gone. And she doesn't know how to fall asleep without you so she calls out to you to come and help her fall asleep again. So you will need to look at helping your DD learn to fall asleep independently. Again Tracy's books have some fantastic suggestions on how to do that. For your DD's age, Tracy details a process called Pick Up/Put Down (or in fact, just put down for a 1 year old). Again I really recommend you read through the books, or the sleep interview posted at the top of a couple of the sleep boards, to get Tracy's detailed instructions on how do use Put Down to help your DD learn how to fall asleep independently.
The only other thing I wanted to mention (in case I haven't already set you enough work

) is that your DD's bedtime seems quite late. My DS (who is also just 1) and many other babies I know around his age, are going to sleep at about 7 or 7.30pm. While it might seem counter-intuitive, an earlier bedtime means for a better, longer sleep for babies because they sleep better when they are less OVERtired at bedtime.
Munch1, this will not be an easy task and will take you some time to work through these issues BUT if you determine your new strategies, based around Tracy's suggestions, and remain CONSISTENT with the new way of doing things (as consistent as you have been with the old way of rocking/holding to sleep) your DD will learn the new way and slowly will come to need you less during the night as she learns to put her self to sleep, and back to sleep during the night. We are here to help you as much as we can so feel free to post any futher questions you have.
Good luck
Jo
