Hi N.,
I'm sorry it didn't go well for you! I know how hard CIO can be. It is what we did with our first daughter and it was TOUGH. Harder on me than on her, I'm sure. She does not seem to bear any lasting scars (she's now almost 6). *I*, however, still recall those 3 days with perfect and lasting clarity. =)
If it makes you feel any better, I think when you went in to check on her, probably she had the "dazed" look because she was about to fall asleep.
In an effort to avoid CIO with our second child, I read "On Becoming BabyWise" by Gary Ezzo on the advice of a friend of mine. It worked GREAT for us. Our little one never cried it out and slept through the night at 6 weeks; it was very painless. As I followed the method with a newborn, I'm not sure what he recommends for a 1 year old but I know he did cover that in the book. He does also address not nursing them to sleep (as they do not get a full meal, and they never learn to fall asleep on their own).
My suggestion is to try nursing 30 minutes before bedtime, and then bath (or story, or whatever), then bedtime. The trick is to put her down early (7pm or earlier), when she is tired but not exhausted. Exhausted babies are not able to self-soothe and she won't be successful. Lay her down with her favorite lovey (blanket or doll, pacifier, soft music) and let her try to fall asleep on her own. If she begins to fuss, walk in and quietly tell her, "Mommy is here but it's time to go to sleep." and then leave the room. She may fuss a bit, but that is ok. It's all part of your baby learning to settle herself down. Give her a few more minutes and then if she is still fussing, go back in and tell her, "Mommy is here but it's time to go to sleep." Just be gentle with her, lay your hand on her if you want, but don't pick her up. Rather than settling her down, that would rile her up again. I'd try this with naptime first, and then work your way up to bedtime. Remember, she is looking to you for cues on what she is supposed to be doing, so let her know what you would like her to do and help her learn it. You may be surprised that after some resistance (because that's what toddlers are programmed for!), she will fall in with whatever you want to happen.
I hope this helps. Take heart. Remember that learning to go to sleep by herself will be an extremely useful skill as she moves on through life. Like many other stages you'll go through (learning to walk, learning to talk, potty training, and learning to read, to name a few), your child will be frustrated as she wants to do things but doesn't have the skills yet to master the task. It's ok for her to be frustrated because that is what will compel her to learn and master new skills. It's hard to watch our precious babies struggle, but it's what we have to do to help them be successful. Hang in there!
