I have have one client with Sheehan syndrome and she could never fully
breastfeed. I naturally wondered about the BF management. It was not perfect
but then again, it really seemed to be so much more difficult for her to BF
that I did not "encourage" her to continue when she expressed her desires to
gradually wean.

As for the clear blisters on the nipples, I would say it is likely to be
herpes unless otherwise proven not to be. So be careful! Could this be why
her baby is having breathing problems? If he is already contaminated,
couldn't she continue breastfeeding if his condition permits and if her pain
is not to intense? R. Lawrence has a goog section on this in her book.
