three year old throwing up only at night
My three and a half year old has thrwn up at night only 7 of the last ten days. He also has diarrhea. During the day no vomiting, maybe one case of diarrhea per day. I have taken him to urgent care and the ped twice. Always told its a virus. They are testong stool but no results yet. No fever. No one else in our house has caught it and no one in his prek is sick. I'm going nuts and starting to convince myslef he has cancer. Please help!!
