Does it still increase supply to have baby nursing without removing much milk or is the actual removal what increases supply? My twins are not good at milk removal at all but I know the skin to skin stimulation should count for something. I am wondering if I'm mostly wasting my time to have the babies nursing if they are only removing 2-12 ccs and should mostly focus on pumping (I'm pumping at least 12x/day with a hospital grade pump).
