Bottle Strike

Baby on bottle strike suddenly only want to latch. Currently 1 yo, I gave baby 2 meal a day. So she actually miss both her milk feed while I'm away working. And she only want to be nurse now. Baby yet to sttn and her percentile drop from 75 to now 45. What can I do to make her drink from bottle again? I can't be there for her to nurse all day as I need to work.
