A: It could be that your baby has developed an intolerance to other things besides milk protein -- like wheat, eggs, or peanuts -- which are also transmitted via breast milk. Try removing these foods from your diet, one at a time, and see if you can narrow down the culprit.
If not, and your baby is still experiencing symptoms -- especially persistent bloody poops -- you should see your pediatrician. You might even want to bring a dirty diaper as evidence when you go in. He or she may recommend you see a pediatric gastroenterologist to rule out other problems like a bacterial or parasitic infection, an anal fissure (a tear in the tissues around the rectum from passing hard stools), or colitis (inflammation of the intestines, which can be genetic).
