Quoting Blazian baby:" so I have to breast pump because LO is still in NICU .. ive noticed that one boob is bigger and always ... [snip!] ... the same amount as the small boob. and also HOW MUCH milk do you pump before you feel its empty and how long does it take??"
Try and pump consistantly like ever 2-4 hours. I had to start pumping for multiple reasons. My milk took a while to come in because I had a post partum hemmorage so I had to supliment until my milk came in and the little guy wont latch so I just pump now. I pump every 3-4 hours I did start drinking mothers milk tea to help it come in better as well. When it finally came in I wasn't producing much and I started drinking the tea and it slowly increased my right side does tend to produce about an oz or so more then the left though but on average I can get a total of 5-7 oz with each pumping and I pump for 20 mins.. I also have a double breast pump and have this special bra that I use so I don't have to hold the breast shields.
