At just one and a half years old, Caleb was taken to the hospital with welts up and down his body.

The cause? A small cashew that caused inflammations throughout his body, according to his mom Janey Yu.

Coverage of peanut allergies on Globalnews.ca:

He could hardly breathe when he made it to the emergency room.

There were welts coming up his body, welts in his groin and it seemed to be moving towards the chest area, she told Global News.

But that wasnt the last of his reactions to nuts; hes endured similar ones twice now.

Every time that its happened, I am terrified, Im terrified of losing him, Yu said.
