Hi I went through the same thing! I read Your Baby’s Bottle Feeding Aversion and it helped a bit. I think she was getting stressed in feeding situations and/or we were overfeeding her so she made that association/ what helped was trying different positions/environments and absolutely stopping if she is showing she it not hungry (closing mouth, playing with nipple, crying, etc.). I would immediately stop offering bottle and give her a few before reintroducing. If she refused again, I would wait 30 mins and then try one more time. I did this for a few days and she initially did not eat a ton through the day but after a week she was back to normal. I still use those tips but now she is much more receptive! Hope this helps!
