Won’t take a bottle

Hi mommas! I’ve returned to work a few weeks back and my son is 12 weeks old and EBF. However, we’ve tried several different bottles.. 6 to be exact and he just refuses to take any of them. Doesn’t take a pacifier either. He gets extremely upset and cries whenever we try to feed him with a bottle. My hours are picking up more at work, and I’m at a loss at what to do to help him adjusting to eating out of a bottle. Any tips for a stressed out mommy!?
