Night time feedings, 5.5 month old?

My 5 1/2 month old baby still wakes up 2 times to feed. I tried to put her back to sleep; but she doesn't sleep unless I feed her. During the day she takes about 24 oz. and some solids. Only with night feedings she takes the amount that is good for her age, which is 26-28 oz. Will she ever want to sleep without feeding?
