4 month sleep schedule

What does your sleep schedule look like for your babies? My babe is 4 months, 1 week and I’m always paranoid she’s not getting enough sleep and I’m not setting the correct sleep patterns for her. She isn’t in the crib yet (starting that process in 2 weeks) which also terrifies me!

Also, when and how do I start getting her to bed earlier? Right now she goes down around 8:30/9pm. Is that too late for her age?
