Help! Need Advice, Won't Take Bottle

Jamie
Our baby girl starts daycare on Tuesday. Since birth we have been breastfeeding, but using a bottle to feed about once a week or so to be sure she would take a bottle. Now suddenly this last week she won't take the bottle! She gets really angry and just screams. She has to take a bottle next week all day when I go back to work. What can we do?!?!
