Thanks for your query
Your daughter is having enteritis
which is usually viral in nature,but i will suggest a stool examination and if there is any infection she may need a course of antibiotic.
In the meantime i advise you to maintain proper hydration give oral rehydration solution sip by sip after each loose stool
.give coconut water,curd, banana.boiled potato,give lactobaccilus sachet for 2 to 3 days.
In case symptoms do not subside take pediatric consultation.
Your daughter will be fine.
