Question
My child had diarrhea four times three days ago, and then had a fever the night before. After taking fever-reducing medicine, the doctor examined them carefully during the day and said it was a viral infection. However, they only had one episode of diarrhea the next day and were sent home to be observed closely. They were told to be admitted if they still had a fever, but they never did. This afternoon at 6 PM, after drinking formula milk, they vomited everything up. They also vomited after eating twice in the evening with no other symptoms. What could be the cause?
