Hi
Any loose stools for more than 2 weeks should be evaluated.
Was any new food/ new formula introduced?
If he is on breast feeds, you may continue with that.
If he is on formula feeds, you might have to temporarily stop the formula and try soya milk/ lactose free preparations.
You may give him plenty of fluids like
ORS, plain water, vegetable soups, porridge, rice based food, Boiled and mashed potato, Banana, plenty of curd.
You may also give him
probiotic sachets like Econorm- 1/2 sachet twice a day for a week.
You might have to give him Zinc syrup for 2 weeks.
If after dietary modification too,
diarrhea does not stop, stool analysis has to be done for various
malabsorption.
Keep watch on his weight gain and activity- if
weight loss is seen and activity is low- its a matter of concern.
Hope my answer helps you.
Wish your baby a speedy recovery.
