Like I said earlier on this thread our dd has thankfully been a good night time sleeper. I absolutely would not have coped with a bad sleeper being so poorly. I wonder if she had instincts for this and knew to "behave"? As if newborns can choose to behave! But I do sometimes wonder.
We started a bed time routine when she was about 6 weeks old. I'm sure it really helped. As others have said if she isn't asleep by 8 she can't get the 11hrs she needs since we have to be out of the door to nursery at 7.15. I've been lazy with times this week since I'm on annual leave and so she's waking at nearly 8... Got to try to fix this before Tuesday otherwise the poor thing will be exhausted!
Dd is 18 months old. We used to do bath, bottle in rocking chair, short cuddle to burp then bed. Since about a month ago we have changed it - switched to quilt not sleeping bag so it's more like a big bed, and ditched the bottle and switched it for a mug of milk. Its a more grown up bed time now. Tea is at about 6.30 (nursery give her a tea at 3.30 too!). She has a big bath at about 7.30 (no longer in the baby bath!) which she loves. She has a story read by one of us while sitting on the other's knee usually, so that it's easier to help with the mug (though she's getting pretty good now!). then quick cuddle and into bed by about 8, in theory. We use the same words every night - night night, sleep tight, love you - and she says night night back and seems not to complain. She usually has a big grin on her face like it's a game 
If dh can get home early enough he gets about an hour and a half with her. It's just the way life is sadly. If she stayed up with us she wouldn't be able to function at all having to go to day care. It would be lovely in some ways to have her on our timetable like freedom and go to bed and get up all together. But I do value the time dh and I have together after she is in bed and think it's important for our relationship (when he isn't catching up on work and I'm not falling asleep!) Plus, when would we clean up the kitchen?!
