(CNN) -- Two-year-old Ethan Wily had a cold recently, so at first it wasn't surprising that he started coughing last week after eating some pistachio gelato.
But he started coughing up mucus, and then gasping for air. His parents gave him an antihistamine, but it didn't stop the reaction. By the time the boy's parents brought him to their local hospital, he could barely breathe.
"His face was really swollen. He looked like an alien," said Ethan's father, Preston Wily of Lehi, Utah. "We didn't have any idea an allergy could be so bad."
He said the child had shown only a somewhat mild reaction to peanuts before this.
It seems like more and more children in the U.S. are developing food allergies, and there's data to back that up. The number of kids with food allergies went up 18 percent from 1997 to 2007, according to the U.S.
