Just quickly trying to fit in a few comments before being overcome with far
less entrancing everyday stuff....

Kathleen Bruce, you raised this case. Yes, there is a difference, but sounds
also as if a lot of obfuscating
could be going on so that he gets to manage this case without maternal
interference!

If he knew more about breast milk, he would not be discarding it in favour
of such an inferior product with a baby who badly needs it! This has the
hallmarks of severe cow milk allergy, and we have also seen a baby with what
looked like bad acid burn from waist to thighs due to this. His mother went
out and spent $800 on an electric breast pump to ensure that she never had
to resort to ABM again (her idea, not ours) and took every skerrick of cow
milk product out of her diet, then life returned to normal as the baby
recovered.

Some people use "allergy" and "intolerance" as if they are the same thing,
but although the symptoms can be pretty much the same, antibody production
ie an immune response is involved in allergies, whereas this does not happen
with an intolerance problem in which the body simply cannot process the
offending agent but does NOT manufacture antibodies to it. Examples are
various sugar intolerances. Phenylketonuria is an intolerance problem with
phenylalanine, where the sufferer does not have the biochemical pathways to
be able to process
this amino acid. (Some may not agree with classifying this as an intolerance
problem, but it depends on how you define these things!)
