Pumping w/ baby in NICU

Brigette
My little man is 13 days old. I'm pumping on an average of every 3 hours. I sometimes get an ounce out of my left breast and half an ounce out of my right. I haven't given up, but I want my supply to go up. I'm pumping bedside as well so I can see him while I'm pumping! Help please!
