Passing mucus in the stool is not harmful in and of itself, but more common causes of mucus in stool includes bacterial overgrowth and food allergies
and sensitivities. They are often easily corrected with dietary changes and supplements that may require treatment.
some other causes are :-
* Babies suck on to anything they can lay their hands on, including their own body parts. This along with the drooling
would result in an increase in the amount of saliva in the mouth. This saliva may contain irritants or germs which on reaching the intestine may result in a stomach upset
causing runny stools containing mucus.
It is important to take the advice of the physician so that the underlying cause resulting in the mucus could be treated first.
If the condition can be correlated to any element in the mother’s diet in breast feed babies, then it will be essential for the mom to revisit her diet .
Hope I have answered your query.
