Help! baby refusing bottle

My baby is 10 weeks old and exclusively breastfed has now decided to start refusing a bottle. We were incorporating a Dr. Browns bottle into one feeding a day but all of the sudden she won't take it at all as of last week. Took her to daycare for the first time yesterday and she refused every time they would try to feed her. Has anyone else has this problem? What did you do? I can't leave work to feed her every time she needs fed. This morning my husband tried giving her the latch bottle and she refused it as well.
