A.S.
Alot of times when babies first become mobile they are so excited and want to try everything out and have a hard time falling asleep or stand up and then can't figure out how to get down etc. You haven't said how long this has been going on, but I know with my son it only took like a couple weeks and then he was "old hat" and went back to the routine. My son also was waking up for at least one feeding at night till he was almost a year old. Have you tried laying down with her in your bed? Pick her up, give her a bottle in your bed and maybe she will drift off to sleep with the comfort of Mom nearby?
