I notice lately that when I pump and it slows and eventually I stop getting milk in a session, I still have alot of hard "blocks" in my breast that I think are filled with milk. No matter what I do, I can't seem to get the milk out of those hard areas. The rest of my breast is soft and I haven't gotten nearly what I'm supposed to. (I usually get 8-10 ounces of milk per day at work. Today I got 5.5 ounces but I feel like there is still more milk being retained in my breast.
