You're both right and thanks, S'smon for the link- once again, very interesting info.
I've decided to heck with trying to stuff 15+ tablespoons into my lo, I know it's impacting her bfs as she started to refuse full bfs, would only feed for 3-4 minutes which would put me into a panic about my supply and early weaning so I would offer again an hour later. This resulted in 9 "snacks" of bfing yesterday

Who has time for that?!
Today, I said enough of this craziness and I went back to our normal routine, 4 hour feeds and solids 1.5 hours after. She bf like a champ and took 3-4 tbsps of solids at each meal and I didn't push for more once she showed me disinterest. Funny, she didn't crank out, had wonderful bw naps and went to bed tonight like a charm.
She's not "skinny", just petite, so I'm not going to worry anymore (at least for this month

).
