Sleep schedule

What are your babies sleep schedules like? My girl has been waking up at 5:45/6 AM even when going to bed around 9 or 9:30 😭 and I have a newborn so I’m up all night…some days she naps early around 10 AM. Her naps can be 1-2.5 hrs. I want her to sleep later in the mornings if possible. She’s too fussy and just miserable if she doesn’t nap. I’m nervous to wake her from her naps bc when I’ve done that she’s a mess and sooo fussy. Any advice appreciated!
