I'm planning on using my Medela Pump in Style with baby #2. I need to pull it out of the closet and check the motor, but I only used it heavily in the beginning when DD was born and then only rarely after that, so I'm guessing it should still be in good shape.
My question is, which of the parts do I need to replace? I'm assuming membranes, but what about the valves or the entire shield? Tubing? Storage containers?
