Skipping naps?

Cynthia

My 11mo daughter has been getting up later than usual recently at around 9:30-10am. Also, her naps are supposed to be at 1pm but now waits until around 5 to nap (sometimes not until 7) and since her naps are so late she goes to bed around 10-12a... I don’t know why to do, how this even started or how to fix it. HELP 😅
