Baby suddenly waking earlier - please read before voting!

My girl is 8 months old.

Since 5 months, she sleeps through the night and wakes up at 7:30-8:00am.

All last week she’s been getting up at 6:00am.

Do you think she needs an earlier bed time?

8 month sleep regression?

Teething?

Leap?

Combo of these?

She has a very consistent bed time routine already!
