What’s a good bedtime for a 9 month old

Bri • Married and mother to babygirl💓

My daughter is 9 months and I’m trying to figure out what would be a good bedtime for her . She wakes up each morning at 9:00 am and as of right now her bedtime is anywhere from 10pm to 11:00pm. It’s been like that since the beginning but my husband thinks since she’s getting older i should change it .
