Hello...I understand your concern.
It seems your daughter having having viral diarrhea....I am sorry for her symptoms. But be assured that it is not dangerous.
Once it starts it will take 5-7 days to completely get better.
Unless she is having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting...you need not worry.
There is no need to use antibiotics unless there is blood in the motion. Antibiotics might worsen if unnecessarily used causing antibiotic associated diarrhoea.
I suggest she be given zinc supplements (elemental zinc 20 mg once daily for 14 days) & ORS (Each small packet mixed in 200ml of potable water and keep giving sip by sip) as hydration is very important and crucial part of treatment. If there is vomiting you can use Ondansetron (as prescribed by your physician).
Regarding diet - Avoid fruit juices as they might aggravate diarrhea.
But she can take fruits as such as they contain fiber and help in formed stools. She can take zinc supplements & ORS apart from normal vegetarian porridges & soups.
Most crucial part is keeping her well hydrated. Make sure she passes urine at least 6th hourly once.
