my question is what kind of pump do you use ? I know it cost a pretty penny but the medela "pump in-style" has worked wonders for me , every other pump I have used doesnt express any milk from me.. Also, if its convienent try nipple stimulation for a few minutes before pumping and keep a few pictures of your LO in view >> REMEMBER you are in love with your child (which is why milk flow is easy when nursing) pumps SUCK "literally< lol" and you are not in love with it so it makes it harder to express milk that you want to. Good luck!
