Help! Increase BM supply

Anne

I want to EBF my 4-mos LO, but since he was born he screams whenever I put him to breast so i end up giving him formula. I suspect this is due to my breast milk supply. When I pump, i only get 10-20ml.

I have taken oatmeal, fenugreek, moringa, red dates, malt drinks, almond milk and even Domperidone, i’m also pumping 3-4 hours for a week now but todate my yield is still the same. It’s very frustrating. How do I increase my BM supply?
