My daughter was also not a sleeper. In order to get her to fall asleep, we did nothing to make it "worth her while" to get up at night. We would go in and physically lie her down and tell in a sweet voice to go to sleep. We would let her cry 5 min. and then go in again, physically lie her down and say the exact same words and let her cry 10 min. We would increase it by 5 min. and after a few nights, she learned to fall back asleep. They were long nights but well worth it! Every once in a while she would wake up again crying but we would lie her down again and she would fall asleep. Some babies don't know that if they wake up that they should just go back to sleep. We saw this on 20/20 or one of those shows years ago. It showed the baby, with an infrared camera, going through the learning process of learning to just fall back asleep. Maybe it will work for you.
