Thank you all for your suggestions! Sorry to be confusing with the last post...partly due to me being confused myself, and partly because I was using some Babywise terminology (e.g. late evening feed; first morning feed) without explaining myself.
Basically, the gist of what I was attempting to say is that Anniston will sleep 8 hours when put down at 8, but if I wake her for a late evening/dream feed, she will not usually budge enough for me to give her much food (if any at all). This would leave her sleeping until about 4 either way. So the issue is not whether she's sleeping through the night...it's that she won't consistently do it in the time frame that I would like. Not really a big deal, I know.
Oh well, we're trying different things to hopefully make the late-evening feeding work (keeping her up a little longer, doing feed with bottle, etc.), and I will let you know how it goes :). We actually HAVE had a couple of nights this week where she ate a lil at 10 and slept until about 5:30, so we have progress!
**Just had to give a shout-out to my sweet cuz, Megan, who had her ADORABLE baby boy Ridley on Thursday! I'm so glad I get to share this new-mom phase with you, babe!
