Honey, there is only one way to get a baby to sleep through the night. You have to stop going to her! i know it's hard. Believe me, I never thought I'd get through that first night of trying it with my oldest. But I did. And the next night he only cried once. And the night after that he slept through.
You need to decide what the schedule is. If you are going to feed her in the middle of the night, then decide how many hours after she falls asleep that you will feed her. And then only go to her at that time. Yes, she will cry a really long time the first night. But then she will eventually cry herself to sleep. And the next night, it won't be as long. But if you go to her after a long time of crying, then you are teaching her that eventually you will come, so keep it up! You have to teach her that there is no point in crying, you won't come. That's when she will stop.
