I really use so few habermans that these completely uniform "lip pads" as i
call them  (I'm not sure they ARE physiologic blisters as they never form
vesicular lesions and the words blisters to me connote something negative
which I am not sure they are.......I don't even call nipple vescicles that
"disappear" before the next latch-on as "blisters" but ductal epithelial
skin "covers" a gestationally related proliferation over the ducts.
Blisters as I understad them, in the true sense would remain vescicular
without spontaneous resolution, but since these so called nipple blisters
are "absorbed" or "flatten out" after the negative pressure is no longer
present, they do not stike me as "pathologic or abnormal" so I do not treat
them thus.)   I only see these circumlabial pads on latex nipple feeders or
a few breastfed ones so I can't honestly attribute it to the haberman.
maybe you could call one of the ladies  who do oral motor work, (nashville
conference) to see if this  is physiologic or pathologic, please let me
know.......ruthy.
