There is no evidence that PPB's in breastmilk cause any problems.  How
is it possible, in those cases where there is a question, of separating
prenatal exposure of the fetus from postnatal?  Eh?  The risks of
formula feeding should not be forgotten.

"Breastmilk is assumed guilty until proved otherwise.  Formula is
assumed innocent until proved guilty".
