Hi. I was debating whether or not to respond to this since I am nowhere near as experienced as many of you - I have only just recently become a bfing educator. However, I have personal experience with this, and since no one has mentioned this, I thought I would. I first noticed blood in my daughter's stool when she was 6 wks old. We spent the next 6 wks going from one dr to another. I totally eliminated all dairy and soy products from my diet. After 6 weeks of this diet, there had been no change. Our dr ordered a lower endoscopy, and yelled at me for not being clear enough as to how much blood there was in her stool (how was I to express this???). Apparently, her intestines were much worse than he expected. He did a biopsy and could find no other reason than that she was having an allergic reaction to something in my bm. He suggested an elimination diet, which I tried for a few days but this made my life so miserable that I switched her to Nutramigen. Within a matter of days the bleeding stopped. I cried for days over having to stop nursing, but could see no other alternative at the time. When I became pg with my son, I did some research (I never believed that it was an allergic reaction). I found, on-line, a lactation consultant who suggested that the problem could very well have been caused by the fact that I am an over-supplier, and she was therefore getting too much foremilk. She gave me some "tricks" to try if I started to notice problems with my son. I did notice these problems, tried the "tricks" briefly, but became discouraged too quickly. I ended up finding a happy medium - I alternated nursing with formula. With my third child, I expected to have to follow the same course of action as with my son. However, I was more educated and had more support. I have noticed blood in her stool on occasion (all during the first few months), but I have diligently applied every techinique I can find to manage my over-supply, and I can proudly say that I have seen no blood (or any other signs of a problem) for months now. This has all been a very long way to ask - does the mother have an over-supply problem? If someone could have told me how to manage it (or that it even was the problem), I would have been able to exclusively nurse all three of my children. Hope this helps...... Melanie
