My supply had dropped quite a bit in the last few days I don't know why or what I can do to get it back up?! My son is 5 months old I don't pump on a regular basis but when I would pump,i would normally get 3-5 oz combined easily. Now I pump and am lucky to get 1 oz. I had to leave him overnight and he went through my freezer stash and I want to build it back up but I'm only getting an oz when I pump. Do I need to change my diet?. Please help!!!
