Early morning waking

So my 9 1/2 month old LO has been waking up at 5:30am almost everyday (some days I’ll get the occasional 6:15 wake up) for the past month or two. Her schedule looks something like this:

Wake up- 5:30am 😞

First nap- 9:30am until about 10:45am

Second nap- 2-3:15

Bed- 6:45ish

Any suggestions on what to do to help her sleep in later? We use the Zip a dee Zip, sound machine, have black out curtains. I’ve tried adjusting her naps and bed time but that didn’t help.

She’s so good and just lays there and waits for me to get her. She eventually goes back to sleep on days that I take longer to get her. Should I keep her awake or let her go back to sleep until 7am?
