About a week ago I noticed my left breast was getting fuller than usual. LO does prefer the right side so I assumed that during the night he's just sticking to the right one. However the last few days my nipple has been really sore when he's feeding. He did bite me really hard at some point in his sleep a few days ago and I literally had to force my nipple out of his teeth as even putting my finger between the gums didn't loosen them! Anyway, since then it's been really sore for the duration of any feed on that side and today I noticed a white blister on the nipple. I read the Kellymom advice on what to do but I just wondered if anyone else has dealt with a blister quickly and easily?
