Hello
I think she might be indicating to you that she is ready to transition to 3 bottles hun... As for the night feed, it's up to you, but I would be leaning towards shifting those calories to day time bottles, IIWM.
As for solids, I have noticed that many LO's go through a strange phase with refusal around this age after being all gusto for a few months... I wouldn't worry at all about this as solids before a year are only for learning, not nutrition. You really do want her formula intake to remain close to 24 ozs a day.
I would attempt to start shifting her night bottle ozs to her first AM bottle by reducing the night feed by an ounce every few days and then adding it to her AM bottle... she will likely get to a point that she stops waking during the night before that bottle is gone - she will find it too much hassle to wake you to only get a couple ounces
Some suggest diluting the bottle, but I found that didn't work as well as LO still got that full feeling from the extra water.
Maybe try something like this:
Wake and bottle
Solids an hour later
Nap #1
Lunch
Bottle before nap #2
Dinner
Bottle and bed
