My son is 5 and he went threw this during Christmas week... It is a Stomach Flu and most likely the FLU if he is cough and sneezing and runny nose too... I know it is scary with the fever so high... but just try to give him Motrin and alternate with Tylenol... That is what my doctor said... And try to keep him Hydrated. And don't give him immodium... it needs to leave his system... WASH YOUR HANDS ALOT! It will be over soon!
