Hello Lactnetters, As a way of a brief re-introduction{since I've been
nomail for a while }, my name is Susan .  I'm an RN doing mother-baby in
Texas.  I also teach prenatal BF classes and wrote and teach a class
called "Breastfeeding for the Employed Mother."  I am very slowly
working toward becoming an LC.
  I have a question for  "y'all."   The guidelines put out by the Human
Milk Banking  Association {my edition is about four years old} state
that  breast milk should not be stored in polyethylene bags , e.g.
Bottle liner bags, because this type of bag robs the milk of up to 60%
of its IgA.  The students in my class last night wanted to know if this
also applies to using these bags for just a bottle-feeding of EBM.  In
other words, how much IgA is lost if the EBM is not stored but poured
into the bag for a 20-minute feeding?

  A question for you, Jack.  You stated a couple of days ago that the
antibodies in breast milk probably do not enter the baby's systemic
circulation but none-the-less help prevent illness.  Do the antibodies
remain in the baby's gut?  If so, what is the mechanism by which they
protect baby?
