Bottle Aversion HELP

Hi,

My 12w old a month ago slowly started refusing the bottle. Went to the doctor and was suggested a different formula. Issue continued. Fastforward few days after, when she caught her older brother’s virus, she a 100% refused bottle. We had to go emergency so they can feed her by tube. Turns out she had acid reflux and was slowly refusing bottle from the irritation. Unfortunately it full on created an aversion. We were at hospital for 2 weeks. They let us go after a day of her taking bottle. 2 days later it got so bad we had to go back. They suggested going back to regular formula as the one suggested by doctor earlier smells horrible. It worked 3 feeds in a row. They let us go. Been a week of this still continuing. I caught my son’s other virus and so i was avoiding holding my baby so she doesn’t get sick again. My MIL has been helping. She’s able to soothe the baby but there’s still a loooottt of struggle. We tried(different bottle, different nipple, different room, different positions, different person giving milk, different formulas, feeding before she asks, after she asks). She’s on antiacid and inclined so she can digest better. What else can i do??? I read all articles online, i don’t know what else to try. She cries during feeding and even in between all day. She doesn’t sleep much during day so she sleeps better at night. I’ve seen like 10doctors. 8 during hospital stay. 1 at clinic and her paediatrician.
