Little one refusing bottle & starts daycare in a week

I have been breastfeeding primarily & pumping when we would go out. My daughter was fine & took the bottle with no issues even if it was only a couple times a week. Until about 2wks ago when she threw up after drinking from the bottle & ever since then she has refused it. She is 11wks and I am due to go back to work 6/13. I’ve been attempting to get her to drink from the bottle but that’s been to no avail. Does anyone have any tips because I truly don’t want her crying nonstop while I’m away for 8hrs.
