Hi D.,
I am a first time mom and my daughter just turned one. All I can say is that the sooner you can get her to fall asleep "on her own", the better! My daughter also always fell asleep while nursing at night and when she got teeth I had to wake her to brush them, which was not good since sometimes that made us have to start the whole bedtime routine over again! I've read a lot of different methods, but I think you have to do a mixture of what works for you and your daughter after you try them out.
Here's what we do:
-Around 8 she takes a bath
-we read a few books
-we turn out the lights and put on music
-she drinks milk (from a cup now)
-brush her teeth
-I rock her for 5-10 min
-lay her in crib, but she is still AWAKE, that's the important thing. She's drowsy, but not all the way asleep.
Honestly, the "books" and "people" say to do this and that she will only cry for like 3 nights. Well, for me that wasn't true. It was off and on. Yes, the crying was awful. I would do the thing where I let her cry a few minutes, go in and pat her, and so on. I even picked her up and just held her for a minute sometimes (one method says it's not good to do that, another says it's fine)and then that was it for the rest of the night. So, really it's just a mix of what I'm comfortable with and she's comfortable with and now I do this routine at her naps too (minus the bath) and it's heaven! She rarely cries anymore, and if she does it literally lasts less than 15 seconds.
I know it's a bit harder when you are nursing at night, which I did until she was 11 months, but really just try to not let her fall asleep. Stop her and brush her teeth. I probably should mention that my daughter takes a pacifier, which obviously helps. I will attempt to be taking away the pacifier in the next three months...but that's a whole new issue, isn't it??!!
Your daughter is younger then when I started, so I say start trying things and find what works best. It's worth it, you will both feel better and be rested once you've found your routine.
One recent article I saw was in Parents magazine, August 2007 issue. It was called "Get your baby to sleep through the night". I liked it because it even had a little quiz first so you could see what method might work best for you.
Sorry this was so long, hope this helps!
