After I pumped for 30 mins (Medela PIS double pump) I kept feeling like there is lots more in there. So I tried hand expressing and was shocked to get a literal spray out of my left breast!!!! This continued for half an ounce I am wondering if maybe manual expression will work best for me! It doesn't make my nipples sore like the pump does. Anyone have experience with manual? Any tips on how to completely drain the breast this way? I have DD's and they are hard to hold onto!
