Well I just dont think moms are ever allowed to get real sleep. My kids are 4 & 7 and I rarely sleep all night w/o interruption, even if the interruption is just my worry over a caugh I hear.
Try to be sure dinner has enough Protine and fiber. These things keep you full longer.
She could be just thirsty, try letting her sleep w/ a bottle of water.
If you do find that the bottle is just what she needs be sure to have it ready before you go to bed. When she wakes feed it to her and then put her back down this way she cannot fall asleep with milk still in her mouth which I think is the real concern for the teeth.
By the way...CONGRADULATIONS! You made it a year. I took a sigh of relief at that point with each child.
