My first son use to wake up crying in the middle of the night and it wasn't until he started talking that I realized what the problem was. He'd wake up with leg cramps. I think the doctor said it's because he was growing.
That could very well be why your daughter is waking up. Maybe try rubbing her legs and see if that helps.
You may also want to check with your pediatrician and see if he has any suggestions for possible leg cramps.
You also have to be careful that your daughter isn't trying to train you to be with her 24/7.
If you go to your daughter every time she cries, even when you know there's no reason why she should be crying, she's going to expect you to come running every time she opens her mouth.
Kids and babies are really smarter then we might think, lol.
