1 doctor agrees

In brief: Varies

It can take a couple of hours depending on the severity of his symptoms.
And what his intake of fluids has been. Does he have vomiting, diarrhea? How many times and for how long? How many times has he urinated? Fever is another variable. Also children who play sports in high temperatures and humidity with out adequate prior hydration can become dehydrated quickly.
