Talk to me about baby bedtime routines

My gorgeous little Ezzie is 8 weeks today and up until now we've been living entirely on her timetable. I'm not in a massive hurry to change this fact but I would like to start introducing a bit of a nightly routine in the hopes of making life easier in the long run. So, my question is this; what's your routine? What have you found works or doesn't work? And when did you start to introduce it? I know every baby is different and so is every household. But I'd appreciate any and all tips out of interest nevertheless.
