She was probably OT because of the lack of catnap? Dylan used to arch his back and fight me, screaming the house down, when he was OT at the bedtime feed. Nightmare. Only did it a few times, but made me crazy each time. Bottles are much easier than breastfeeding (no latching required, instant gratification rather than waiting for a letdown, etc.) so that could be why she accepted the bottle so quickly and easily after refusing the breast.
Let us know how things go in the morning?
