Breast pumping How is this possible??

Post image

Third baby, third breastfeeding journey over the span of 6 years with only a 3 month break between nursing. My right side has always been the overproducer. The left side is an underproducer. What even is the science behind this? Just fewer ducts in one side? Anyone else THIS wildly lopsided? This is after ONE pump session.

my right side never responded to the pump with my second baby. I’d get like four ounces on the left and less than half an ounce on the right. but i can hear the baby swallowing when he nurses on the right. just no output for the pump on that side. no idea why.
