Ok, I just started trying to relactate 4 days ago. I am using a Medela PIS with the original (standard) shields 24mm and went ahead and ordered the 30mm size (now to wait longer for these to come in..) Also, I have DD breasts. It seems like when I pump I am not getting it all out because I can squeeze and get more. Does shield size really make a big diff in how much you can pump? Maybe this smaller size is why I am not able to get more than drops although I know it is also partly due to trying to relactate (which I did post in the relactate forum).
