How does child have a fever to vomit again to do

Consider that the child is suffering from acute gastroenteritis. First, fasting should be temporarily allowed to rest the gastrointestinal tract of the child, and the symptoms of vomiting can be gradually alleviated. If the baby's temperature is below 38.5 degrees, you can use antipyretic paste or warm water to wipe the whole body for heat dissipation. If the temperature is above 38.5 degrees, send the child to the hospital for treatment as soon as possible.
