When I pump, my breast will only give a few squits, 5 - 10, then no more milk comes out. I usually then go to the other breast. It does the same thing. I continue going from breast to breast back and forth until I get no milk from either . I am using a Medela electric pump on full power. It is a double pump, but I only use one, making sure the other side is blocked. I have also tried a different pump, thinking mine was not working, but gotthe same result. Is this normal? In a good pumping session, I get 3 oz, but normally, it is 1-2 from both breast total.
