Hello,
I have gone through your query and understand your concern.
You have to understand that he is suffering from
diarrhoea for many days.
I suspect it to be due to allergic to some of your regularly giving food.
If he have fever or
abdominal pain, then he may have infection by virus or food
poisoning.
If not then it could be due to allergy. As he is 9 months, i think you have started to wean of the child from breast feeding.
It is usual to have some loose stools,
vomiting in the weaning period due to newly introduced solid foods.
But we have to rule out any milk intolerence and food allergies.
It is not advisable to give cow's or buffalo's milk at this time.
Please withdraw these milks and try to identify any allergy to foods like peanuts or eggs you have given or not.
You have to concerned too much about this if he have any fever,
dehydration, abdominal pain etc.
Just give him plenty of water and ORS solution.
Hope this helps.
Please write back for further queries.
Wishing you good health.
