Only my 3rd time pumping amd finally got this much on the pump out of just the right breast. I didn't get anything out of the left unless I did it manually. I was starting to get a little disappointed with the pump. I did it manually the first two times to get colostrum and then pumped to stimulate. Don't give up Mommas! She was born last night. I wasn't going to breast feed at first but she's in the NICU and I felt helpless so I figured that if this is the best way to help my baby I will give it all I've got.
