This may sound silly but since day 1 I have had a hard time telling when my breasts are really empty. I think this is mostly because I have hard time telling when my breasts are full (unless it's been 4-5 hours since the last feeding at which point they become uncomfortable). I feel like because my breasts are large (DD or E depending) they never really feel full and always feel a little limp? for lack of a better word. How do I know that when I'm pumping I'm actually emptying my breasts completely. I want/need to keep my supply up while I'm at work. My other problem is that I have a lot of difficult self expressing because my areolas are so large I can't find the right place to put my fingers. I never get more than a drop (just enough for medicinal purposes). Any suggestions???
