Sleeping schedule

My LO is my first and only so far. We do sleep because it works best for us since she still night feeds (bottle fed now) my mother complains about her schedule because it doesn't fit HER. My daughter goes to bed anywhere between 8-9:30pm and is up between 8-9:30am she will eat a nice breakfast within 30 minutes play and go down for a nap with a bottle and snacks at about 12pm. When she wakes up usually around 1:30pm she'll eat lunch and play non stop. She knows some sign language so she'll signal if hungry or thirsty for snack until dinner around 6/7pm. All of the sleep schedules I see most babies are up at 6/7 am which is super early for us both but is 8-9am such a bad wake up time?
