Dee... sorry I missed your post... OMG your bitten nipple experience!!!!!! mine was only half as bad (about 1/4 of the way around) but I almost shot through the roof at every feed... thankgod for the temp use of formula... and I know I know about vigilance and trusting others... it's so hard, they just don't have our intuition do they? Sounded like you did well remaining calm though.
