What time do you put your baby to bed (a baby that’s less than a year old)?

And what time do they wake up?

I put my 7 month old to bed at 7:30 PM and she used to wake up at 7:30 AM. However lately she’s decided to get up at 6 AM.

I’m just wondering what other people do. I expect her to sleep until 7:30 AM so she gets her 12 hours. At this point I’m wondering if I should change bedtime to 6:00 PM or 6:30 PM if she’s going to be waking up around 6 AM everyday, but I’m scared she’ll wake me up at 4:30 am if I do that. Any tips/advice are much appreciated.
