I often felt like I would just get into a rythym (sp?) and it would all change. DS went from feeding on both sides, to just one and back again - many times. I agree with MR it sounds like you are doing a great job and are following DD's cues, I also agree that at about 5 weeks there is a growth spurt (I believe they have growth spurts every 4-6 weeks in the first year of life... ) and I am glad for you that she is feeding more through the day then at night.
