Kourtney Kardashian realized her son, Mason Disick, is allergic to nuts after an unfortunate incident with peanut butter when he was just 11-months-old. 
"Mason ate some peanut butter and had an allergic reaction to it. He threw up within minutes of tasting it and got hives on his face," Kardashian wrote on her website after the incident. "I called 911, and the fire department came immediately. They suggested that we take him to the hospital, so we did. He was in good spirits the whole time and didn’t even know anything was wrong. He even enjoyed riding in the ambulance. He's such a good boy!"
Now that Kardashian is pregnant with her second child, the reality star says her current diet is very bland.
