Any tips on how to deal with engorged breasts? I have been been pumping since my little guy was born. But unfortunately he can't handle my milk, his pediatrician put him on a soy formula and he's finally able to eat with out projectile throwing up. Now I'm in excruciating pain and engorged from not pumping so much. Any tips on how to cut pumping out with out being in pain or being completely engorged
