Breast milk supply

Madison

I breast feed my 2 week old son. My milk supply has gone down so much. I’ve tried lactation cookies, I’ve tried cluster pumping, I’ve pumped after he breast feeds. I’ve also increased my calorie intake along with my water intake. Nothing seems to help my breast milk supply. I don’t want to put my son on formula because the little bit that he has tried has made him throw up and affected his bowel movements. Is there any old wives tales out there that can help my breast milk supply? Im starting to feel like a failure as a mother because I’m not producing enough milk for my son… help please
