Try giving her a cup or a bottle with water in it instead or just go in and pat her to soothe her without taking her out of the bed.

Babies that age are perfectly capable of sleeping through the night without food. Best of luck. You may have a couple of tough nights on your hands, but just be prepared for that and know that it should resolve itself in a few days.
