I have a 4 year old nephew who is allergic to nuts. I do not know as to how severe it is, but my sister said the doctor told her to always keep an epi shot on hand just in case. I am also getting ready to build a house on a 14 acre parcel and there are a lot of walnut trees on the tract of land. Does anyone have any experience with nut allergies? Should I cut all these trees down to keep him from having a reaction? Or, am I just over-reacting? Thanks!
