I have a few questions/suggestions for you. My baby is almost 9 mos old and he is a LIGHT sleeper and has always been kind of needy during the night so I know where you're coming from.
1. Do you have to put her to bed at 8 pm? Maybe she just isn't all that tired yet. Could you let her play a little longer and get her down later? I used to try to push an earlier bed time on my DS, but once I gave in and just let him stay up til 10, he would go down a lot easier since he was much more tired. I found my LO started to sleep better once I ditched the schedules I had in my mind. He sleeps when he is tired and that's about it. I don't let his naps dictate my schedule either. If I need to go to the grocery store, he'll sleep in the car, ya know? Sometimes he has a "bigger day" than others and needs more naps. Sometimes he's just not tired and only needs one.
2. Have you totally given up on nursing her to sleep? Try to keep her preoccupied for at least an hour or more so she's super hungry around when you want to put her to bed. Give her a bath...my son is always really hungry and tired after playing in the tub. Maybe you could get back in the nursing down habit since IMO it makes it easier.
3. If you are willing to try nursing her down again...Could you put a blanket on the floor beside her crib and nurse her to sleep lying down? Just make sure the space is super safe. You might be able to just nurse her to sleep and leave her there until she wakes up so you get some time to yourself in your own room.
4. I just want to say that it does get better. My son started waking up a lot around that same age. He became really difficult to put down and I had to revolve my night routine completely around him sleeping/waking. I would nurse him down in the bed and my husband and I had to go to the guest room to get any alone time.
5. Now that he's older, he will easily go down for his first stretch of sleep around 10 pm in his crib and give me at least 4 hours in my own bed to myself before he wakes up. Then I'm more than happy to let him come into my bed again. One of these nights, he'll sleep through the night in his crib and I know I'll miss the nights when he wanted to come in and cuddle. He's already done it once but so far, it hasn't happened again. I'm sure he will when he's ready and your daughter will, too. You are right, though. Getting him in his own bed for the first few hours of the night really does make difference.
6. I never let my baby cry it out and I also NEVER put him to bed "tired but awake". Yeah, that method still doesn't work for me despite how popular it is. I nurse him to sleep in the rocker or my DH rocks him to sleep with a bottle. Then he goes down asleep!
7. I know it's really unpopular/taboo and I don't want to start a debate here, but does she sleep better on her tummy? If she can roll over and lift her head up well, you could let her try it if you are comfortable with the idea (It is a SIDS risk for very young babies). My son has been sleeping on his tummy since he was a little over 2 months old. It's the only way he would sleep more than 10 mins at a time. My ped said babies who spit up a lot tend to sleep better that way. He used to fall asleep during tummy time and I'd just let him stay on his mat cause it was the only time he actually got some good sleep. Once he could roll, I started putting him down that way and he slept a lot better. He still rolls onto his tummy if I put him on his back.
8. You could try the swaddle, but some babies hate it. My son screamed his head off when I tried to swaddle him and doesn't even like to be wrapped in his bath towel. Some babies love it, though!
Hope some of this helps. Push through it...you're almost there!
PS, your baby is still SO little. She will start to understand a lot more once a few more months go by. I really think she just doesn't understand the world yet and wants some comfort. I found that when my baby started sitting up on his own, a lot of things changed. He seemed like he was more socially aware and started playing independently. Pretty soon, she'll start crawling/moving around and be exhausted by bed time. You'll get through it!
