The girls left for the hospital by ambulance today. The child's temperature rose to 38 degrees in the day. As they arrived, the temperature dropped and diarrhea stopped. They are giving antibiotics, from which the child is vomiting. Doctors at the hospital are poking me that they didn't leave earlier on an ambulance. Although our pediatrician said to call an ambulance only in case of vomiting and fever, as I did, ?‍♀️ I collected a urine collection container. How to collect it I don't know.
