Bedtime and Naps

What are your LO's bedtime and nap schedule? My daughter is a good sleeper once she does down, but her nap schedule is all over the place, and she often won't go to sleep until 9pm (on the early end). She is clearly very tired before that, but it's hard to coordinate her bedtime routine and get her down earlier. She is 12 weeks old. It would be really helpful to hear what times other babies are napping and going to sleep. I don't even know how many naps she should be taking.
