I have some really sore nipples. Not cracked, bleeding or anything like that...just sore after pumping and the initial start of pumping. Which of course then carries over to actual nursing because I have pumped 2x a day. I found this on LLLI:
Choose a pump with different sized flanges or breast shields
Some pumps have the option of different sized breast shields or flanges. A well fitting flange will allow for comfortable pumping and a good flow of milk. A mother should be comfort- able both while pumping and afterward (this is where I'm different, I'm sore afterwards and in the very start). While pumping, she should see her nipple moving easily in the tunnel of the flange, pulling her areola slightly with it. Her nipple should not rub against the sidewalls of the flange (Jones 2009).
I fit that description. Which tells me that it is not an issue of fitting properly. Are my nipples sore just because of pumping or is there something I should change about my pump or pumping?
Think sore muscles after working out.
