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?
