My situation is similar as you. Just can pump only few oz. each time. my bb also have nipple confusion as now she does not know how to open the mouth wide. then, I try to pump but the nipple was elongated and I felt painful after pumping. I can only pump 1-2 oz usually, but occasionally, 3 oz. anyway, I tried to breast feed her directly since t was the way to stimulate more milk. just try our best as we can. if the body weight gain is ok, then, don't worry about your supply. add oil. la. I am on your side with you!!!!
