night feeding

How often does she eat during the day? If she goes longer stretches during the day I would wake her and feed her more during day hours and especially early evening to get enough calories in that she can and want to sleep at night. My DS had his days and nights flipped when he came home and when I woke him and feed him during the day he would stay awake more and then began sleeping better at night. He was always wiling to eat early if I offered. It took a couple weeks to get him on a better schedule, but it worked.
