I have been bf and pumping since day one...I, however, dont usually pump for more than 5-7 minutes (db electric pump). I have read about pumping longer, but usually around 4 minutes I have 2 oz from each breast. I pump to get 1/2-1 oz more per breast. When the milk settles, there is three levels...am I correct in assuming I am getting both milks? I try pumping longer, but it starts to hurt and nothing more comes out.
