Thank you for your question.
I am Dr. Su S. and I will try my best to help you.
I am sorry for her symptoms.
Incident that happened a few days ago can be due to indigestion.
Today she has mild rise in temperature, 3 times stool and vomiting.
It can be a viral episode.
In most cases viral illness recovers itself with supportive measures.
Try to give rice based food, banana, boiled potato, pedialyte.
If the symptoms continue, stool can be tested.
Bacterial infection should be ruled out.
She may need repeat visit to doctor.
I hope this information will be helpful.
