Bottle Refusal Frustration

Hello lovely ladies! So I’m in a bit of a pickle here. I’ve posted multiple times in other groups about this little situation I have. My son absolutely refuses any bottle or sippy cup. I have a bottle graveyard in my cubbord. I’ve tried every trick there is to it. Taking him outside, letting someone else try to feed him, different positions, walking, in the middle of the night, literally EVERYTHING. I really need him to accept a bottle for my own mental health, and due to some treatments that I need done that is unsafe to breastfeed during. Please mommas, if you have any advice, please share.
