Changing to milk bottle

As I am DL my baby for 3months now, I need to return to work but my baby seems to fuss & cry when offered bottle. He used to be alright with drinking from milk bottle like once or twice a day when I’m resting. But now whenever a bottled is offered he cried out loud until he gets to suckle. My biggest worry is my baby would keep crying without me being ard for him to suckle when I return to workforce. Any advises? Anyway, he doesn’t do pacifier as well.
