Ok here we go again. From my experience & research reflux bubs learn very quickly that when they feed they are going to throw up & more than likely be in pain. As a result they figure out a way to stop from hurting either refusing to feed, being difficult at feed time or taking small feeds more often. By taking smaller feeds more often they will throw up less & in theory be in less pain. Filling up her belly during the day probably won't work as she will probably throw it up anyway!
I know it's tough to deal with, but eventually she will get past it, you just have to persevere with her :hugs:
