This is normal. Gradually baby's "bedtime" will shift from 9-11 p.m. (which you're on the far end of) to 7-9 p.m., or a bit earlier. Probably in the next week or two. I would get my hands on a copy of Healthy Sleep Habits, Happy Child. Training aside, the book will yell you what normal looks like, and how to change your situation if it's not working for you.
