Have you tried giving her a little Tylenol or Motrin? She could be about to cut teeth. Also, is there any chance she's hungry? When C wakes up crying and then goes back to sleep and then wakes up again soon after, I'm pretty sure she's hungry. Maybe offer more during the day? It's funny I'm trying to offer advice when C's only ever slept through the night one time. I feel your pain. :)
See I've thought that, but she's been eating good amounts during the day, she gets her am milk in a sippy with some oatmeal, then a "breakfasty" snack around 9 am, lunch at 12:30, snack at 4, dinner at 6, bottle at 8... maybe a snack and milk at 8?
