Eliminating night feeding...how?

She'll drop the feeding on her own, but for now go in and let her eat. As long as you have her on a good solid routine and bedtime and wake up time are as close to the same every day as possible she'll start dropping the night feedings herself. My son was 4 months (your daughter's corrected age) when he started dropping a feeding here and there, by 5 months it was 50/50 on whether he would wake at night for a bottle and by 6 months he was sleeping through. No feeding water or refusing a bottle or giving a pacifier or letting him cry it out at that point. He just naturally progressed and began sleeping 12 hours straight on his own. Some babies do this earlier than others, let baby decide when she is ready for this.
