I need some advice. Katie has gotten her days and nights swapped. When I try to settle her for the night she fusses and cries unless I hold her right through about 4 am. Then she'll settle and sleep in 2 to 4 hour chunks until I want to go to bed and it starts again. During the day she is perfectly happy being carried around or napping in the stroller. I've tried lights on, lights off, with the radio on music, on talk. Doesn't matter. She screams and fusses from midnight to 4 am. I know the part about sleep when the baby sleeps, but I would like to see some of the world. And I occasionally would like to sleep with her dad.
