It's super common for newborns to have their days and nights mixed up at first. They need sleep to grow, so as long as she is sleeping just keep trying and hopefully soon she will figure out days vs nights

@rainbowbaby3, I try and keep her up but nothing works

@kayla471, she normally sleep from all day beside when she's hungry diaper change

with my first I kept her up as much as I could throughout the day and she always slept throughout the night.

how much does she sleep during the day? she might be sleeping too much in the daytime
