Marcia McCoy asked whether anyone has heard of a scenario whereby a female
child is sensitized to cow's milk protein and later transmits these proteins
to her own children in her breast milk.

I have heard that women whose breast milk contains detectible cow's milk
protein are different from women whose milk does not.  Their blood vessels
are permeable to cow's milk protein, possibly from early sensitization.  I
haven't seen any published literature on the topic, only heard it in a talk
about 6 years ago.  It fits well with other facts on mucous membrane
immunity.
