Please Help! BF baby refusing bottle

2-Step

DS is staring daycare tomorrow and for the last week he has completely refused the bottle. He has taken it before, but now he just screams bloody murder. We've been trying and trying and he simply won't take it. Anyone have any advice? I go back to work tomorrow and I am going to be a nervous wreck knowing he is screaming his head off at the DCP and won't eat.

I have the rest of today to figure this out!
