I think Sweetness caught on yesterday that the bottle was her only daytime option. At her 2 feeds she ate 3.5 and then 4 oz. I still need to look up and see how much she should be getting but at this point any increase is progress in the right direction. And I have decided that there is some consistency to her inconsistency...she has 1 great night followed by 1 horrific night. That's the pattern. We do the same exact bedtime routine at roughly the same time but it doesn't seem to matter. The only thing I have noticed is that the closer to 7:30 she goes to sleep, the better the night is. Last night was 8:20. We did start the bedtime routine around 7 but she decided to go back for seconds and thirds at the all you can eat boob buffet.
So thanks for your help and advice. And I know this is all to be expected and it'll get easier for me. (she's doing just fine). Yesterday was the first time she's had a 'first' without me and it kinda sucked. But I did ok, and was just as excited when I saw it later on that night. And as an aside this is a first that could greatly help our sleep...she took her pacifier out and put it back in her mouth all on her own!! Now if only she could manage that hand-mouth coordination at 2 AM!!
