I just recently cut the night feedings with my 9 month old--she was exactly how you described your daughter--if I nursed her, she would go right back to sleep in her crib, even if she was awake when I laid her down. If I didn't nurse her, she'd just get mad and would not go back to sleep.
I went cold turkey and decided I was going to cut out all night feedings and would not feed her until wake up time. (She had been going on a week of refusing to nurse during the day and waking 3-4 times a night to nurse). I suppose I did a version of PU/PD. When she woke up, she would sit up in bed and I would gently lay her back down. She would sit up, I would lay her back down. She would sit up, I would lay her back down. The first night, she screamed for 45 minutes at the top of her lungs and sat up every time I laid her down. After 45 minutes, she turned off the screaming, stayed laying down and fell asleep about 15 minutes later. The next day, there was no screaming, but I had to lay her down a bunch of times before she went to sleep. It's been about a month since I did this, and she still wakes up typically once a night. I go in and lay her back down, but it usually only takes 1-2 times.
