my 2 year old had diarrhoea 10 days back n she was prescribed zindust drops. but we didn't completed the course then. after that she had vomiting n loose motions then doctor prescribed cefixime and oflaxocin suspension along with lactobacillus drops.after a week she is having loose motions again.now doctor has prescribed metronidazole n oflaxocin drops and zindust drops. what is the reason for her recurrence? she keeps putting her toys in mouth even we try to tel her not to. and is it because of her water sipper bottle?
