breastfeeding dd2 who's 4 and a half months and have suddenly got a really nasty blister on my right nipple. have had a couple of blisters when starting bfeeding with dd1 & 2, always just 'fed through them' and they went away. This one seems to ahve appeared out of nowhere and doesn't seem to want to disappear. In fact it's getting worse. Anyone have any ideas as to how to get rid of it??? Thanks in advance.
