Did you post in ebf? I had to stop nursing about 16wks I think due to soreness as well. But ds was only nursing 1x a day. From what I've learned you'r milk starts to change over about 4m or so to colustrum so that's what could be going on along with supply drop. I'd say either stick through the pain? until your supply starts to rebuild or try to wean until baby is born. DD may stop nursing or not make a big deal of it at all. I couldn't imagine nursing right now, knowing that every day it was getting more painful. When the baby is born, we'll see if he wants to try again or not.
