I have been back to work for almost two weeks now and am pumping away every chance I get. And I must say, I love, love love pumping in the car on the way to and from work. It is so relaxing.
I noticed on my pump that the cones on the flanges cover almost all of the areola, so that only a thin line of areola is outside the tube-like part that the nipple gets sucked into. Do I need a smaller size? Most of the areola gets sucked into the tube along with the nipple. I have an Ameda Purely Yours pump, and I just bought another pump (Lansinoh... just like the PY) so I can keep a pump in the car. And I have small breasts, maybe a B cup?
I get about 2.5 to 3 oz per breast with the setup that I have, when pumping without having nursed.
