Hi C., I'm sorry to hear you're so drained. It seems like there are as many approaches to sleep as there are families! So, I want to chime in with a bit of different advice here. I'm not a fan of 'crying it out' at all. I think it's too hard on everyone in the house. BUT crying in your arms is not the same as crying alone in a bed while you suffer in the hallway. Also, letting your baby cry some in her sleep is not the same as letting her cry while she's wide awake in the dark. I would follow the advice of other moms here and get your daughter checked for an ear infection, etc., to make sure there's not a medical reason for her waking. If she's all clear, the waking is a pattern she needs your help to change.
Here's what worked for me, when my baby was rousing and I was nursing him even though he wasn't hungry. The first night, I picked him up and held him (bounced and rocked) but didn't nurse him, because I noticed that he wasn't rooting around. I figured I would wait to feed him until he asked to nurse. He cried for a while, but then went back to sleep. Then he slept for a long while. The next night I only held him for about five minutes before he went back down (we did that a couple times during the night). His sleeping improved much faster than I had thought it would.
Now, my baby is a BIG boy, and so he's been slower on some of the physical developments - he's only just getting to rolling onto his side at six months. He also prefers to fall asleep on his side, so if he rouses from sleep and he's on his back, he has needed help rolling back over. We try to catch him before he's fully awake, so we don't have to pick him up. He goes in his crib when he's almost alseep (usually around 7:15pm), and it usually takes us a few sleep cycles through the evening for him to stop rousing, but by 10:30 or so we've helped him roll for the last time and he sleeps until 2:30 or so when I nurse him, and then he sleeps from 2:45 until 6:15 or 6:30. Now that he's getting better at rolling over on his own, we're having to go in to him less during the evening.
If you want to chat more off-list, I'd be happy to. send me a note and we can exchange contact info. Just know that it WILL get better, and hang in there!
