My DS was still feeding 2x at night at that age. He was going to bed around 7...we would do a DF at 1030 and then he would sleep from anywhere until 4-5:30am, feed and then go back to sleep until 7. We continued the DF until he was about 7 months old. The DF is still considered a night feeding, but it helps eliminate a wake up call at a time when you yourself are already in dreamland.
Have you tried that?
If you don't want to do the DF, when you think she's ready to drop a night feeding, I would drop the midnight one first.
I think this age is a little crazy. I remember things going a little haywire around this time and DS waking up for more feeds during this period that he usually did. It lasted us a few weeks. I am not sure if it was a long growth spurt or if he was comforting himself and I didn't know enough to know that at the time
, but it did eventually work itself out. He did start eating less during the day as a result and I think that could be why it lasted so long -- it turned into a cycle. It started to resolve itself once I limited what he was eating in the middle of the night (not dropping a night feed, but giving him less). One thing I think was happening was that once he started drinking his bottle, he would relax and fall asleep and then would just keep sucking, so he was probably getting more than he needed in the night. I suspect that your DD's night feedings will work themselves out in a little bit. Hang in there, babies are confusing!
