My 5 year old son cannot look at others plates while eating. He gags daily during lunch with other children, often throwing up 2-3 times a week. If he sees peanut butter on another child's shirt, a piece of wet bread in the dish water, crumbs in a child's cup from dipping their cookies or crackers, or even his own plate at the end of a meal - he begins to gag. He is otherwise a happy, outgoing child. I suggest to him to take deep breathes and count to 10 - but the only thing that really helps is for him to leave the room. He is currently in a home preschool/kindergarten setting, but I am worried about him attending first grade in the fall when he won't we able to easily head for a bathroom or out of the lunch room.
