7 week old won’t take bottle

I’m exclusively breastfeeding my baby but need to get back to work as soon as possible as i’m a self employed dog groomer and have customers I want to keep. I’ve been pumping milk for him ready for when I have to leave him but he won’t take it from a bottle. We’ve tried loads of different bottles but as soon as it goes near his mouth he screams and won’t take any!!

Has anyone got any tips for getting him to accept a bottle of my milk??

Pic cos he’s a pain with bottles but still my angel👼🏼
