up, on average, 12 to 24 hours after ingestion of the offending food by the
mother."

I attended a presentation by a pedictric allergist many years ago.  He
talked about the "leaky gut" of the infant until 6-7-8 months of age when
production of sIga began to seal it off.  In the early months, foreign
protein was readily absorbed through the intestinal lining and into the
baby's blood stream.  Thus allergic reactions could happen very quickly.

As an example, he had observed a baby who was being skin-tested for allergic
response to egg white protein.  They did the skin injection, then fed the
baby a bottle laced with egg white.  Before the baby finished the bottle,
they injection site began to react.

This presentation was probably 20 years ago, and I am going from memory not
from notes.  I hope this discussion continues.
