I started back work yesterday (boo) and am now pumping while at work. I don't really have a problem but I want to make sure this is okay. My right breast is awesome - I can usually get 4+ oz at each pumping. But my left breast is struggling, lol. I usually get barely 2oz out of it each time. I've tried switching the pump around to see if that made a difference, but it didn't. I'm kind of thinking the pump is wearing out (I got it from a friend and its sevearl years old now), but its doing great with the right breast. Is it normal to get so much more out of one breast like that??
