Baby refuses to eat

FC

Help 😭 I’ve tried it all! My 4m old daughter won’t eat. If she does eat, she’ll take 2-2.5 oz MAX and push out the bottle. She was never breast fed and had reflux. She is on meds for it and it seemed under control. I just don’t know what else to do. She’ll drink 0.5 oz or 1oz and be done. If “hungry” she’ll do the 2-2.5

I don’t know what else to try. I’ve increased the nipple size, changed the bottle, changed the formula….
