Both my DD's (#2 still bf) had them and the skin would fall off then a new 'sucking blister' would appear.......never interfered with their feeding, just made me go ewwwww the first time the skin came off Some say they get it because of poor attachment some say because they are vigorous suckers....well DD's attachment is fine and she's a guts so I go with theory #2!

I don't think it's anything to worry about but if you need peace of mind, don't hesitate to go to your GP.
