In a couple of weeks she will probably start sleeping through the middle of the night feeding

That is what Lily did. Once she hit about 2 - 2 1/2 months (I can't remember).It FREAKED me out the first time because my natuarl alarm clock got me up at the time she always woke up, and when she didn't I kept going in to make sure she was breathing! I did that for a few nights and my body said forget it and I finally slept through the night to. Now she knows her schedule because it has always been that way. She goes down at 7:00 p.m and she wakes up between 6:00 and 7:00 A.M. Thats why it is good to get them started on a schedule because they seem to just "get it".
