I have been BF and pumping for the last 5 months. For the last month and a half, I have been getting much less. I am wondering if it is the way I pump. The only way I can get a little bit of milk is to pump for maybe 10 min to start, then take a break, pump again for up to 5 min, .... And the pattern goes on. My milk doesn't really flow at all. The only time I get milk is when I let-down so the continuous breaks make that happen more.
I used to be able to pump for 20 min and get a few ounces (2.5 at most) but now I could spend hours just trying to get 2 oz.
