M.,
welcome to the everchanging world of parenthood. We always say that babies have thier days and nights "mixed up", but in reality (since the uterus was always dark) she has the same schedule now she had before. When you moved around a lot she was lulled and slept, when you ate or sat down or layed down she became active. For her she is on the same schedule, it is just different from yours.
What to do, well all of the "experts" have mostly differing opinions, hence all those books. I will offer mine as well and it seems to fit with many of them, so here goes.
If you will wake her to eat every 2 hours if breastfed, 3 if bottle fed during the day (Iknow this is hard in the beginning but well worth the effort) then swaddle her securely and let her sleep up to 4 hours at night she will rapidly convert to a day time baby. Using food, light, stimulation and short naps during the day then the reverse at night helps her to set the schedule. You do need to respond to her cry's right away as you have been doing but very soon you will see that she responds to the lack of sleep in the daytime with longer hours at night. If you swaddle with her hands in and to her sides she won't startle herself as muchduring the night therefore sleeping longer.
These techniques come from Dr Karp, the Miracle Blanket, and as a lactation consultant practice with babies feeding needs. I hope they help. I teach the "Happiest Baby on the Block" class at The Nestingplace please feel free to call if you are interested ###-###-####.
