Blood in Stool Common Causes
More often than not, blood in infant stools is not dangerous and
the result of something that can be remedied quite easily. The most
common cause is an allergy to dairy, which passes through the mother’s milk
to her baby during breastfeeding. Cow’s milk in particular, triggers
allergic colitis, which is a fancy name for baby blood in stool caused
by a common milk allergy. As long as a mom avoids dairy products for a
while, the blood in stools should stop.
While dairy allergy is the most common, there are other causes of
blood in stool, including certain types of intestinal infections,
(Salmonella) and even rectal tearing caused from straining while passing stool or
constipation. However, the majority of cases are harmless and temporary.

Luckily, it can be remedied by slowing down gastric emptying, which is accomplished by increasing baby’s fat intake. How do you do that? Before breastfeeding, pump off the foremilk which is often lower in fat than the milk that follows. Also, consider using breast compressions to increase the amount of fat baby gets while nursing.
While it is never advisable to self-diagnose, finding bright red blood in stool does not necessarily mean there’s a serious problem. If your baby is otherwise playful, happy and appears to be normal, it’s probably okay to wait to see your doctor, rather than rush off to the emergency room. However, if blood and mucus in stool is accompanied by vomiting, diarrhea and/or fever, seek treatment immediately as a precaution.
