A.N.
I know its so frustrating when they get their days/nights confused. Try this; when she sleeps during the day try to make it where she's in the living room so it's light in there and do what you have to. meaning, vacuum, do chores, dont keep everyone quiet. when it's bedtime, start a routine that tells her it's night...warm bath, bottle, book, diaper change. Dont play with her too much at night and if you have to change her dont be all animated like you would be during the day. ('did you go poopoo? sort of thing). In other words teach her day from night. It still will take a bit though so try to be patient. Good luck!
