In my experience, the bloody stool babies are almost always rapidly
growing babies.  I have a feeling the bloody mucus would never have
developed in most of these babies if:
1) the mother had "snacked" the baby frequently, one breast at a time
2) the baby had not been exposed to other allergens, either directly or
perhaps indirectly through the mother's diet.

I have a sense that these babies are perhaps from allergic families, and
that the irritation caused by foremilk-flooding creates a gut that is more
susceptible to bleeding when other irritants are added.  I think taking
the baby off the breast, of course, is silly, but that's what they tend to
do around here.

Sometimes the mother's supply drops so badly during the traditional time
off the breast that the foremilk issue is camouflaged for a while when the
baby goes back to breast.

I'd go over the mother's breastfeeding management with her, as well as
potential allergens.  I think it's a big, big piece of the puzzle.

Thoughts from others?
