Donna: there are a number of excellent pediatric g.i. among us but until you hear from them... often this blood can be from something very MINOR... BF need NOT be discontiued. they are not related.. though there can be a realtionship between what mom eats and a reaction in the baby. sometimes there are small tags internally that break off and bleed, often they can not be sure what or why BUT if baby is thriving and doing well... i do not racall the many other minor things that can cause this but the are all benign. Mom should see a breastfeeding friendly pediatric gastro and continue to breastfeed. Patricia
