Yep, definitely no peanut butter in our house. We also have eggs, milk, and most tree nuts to worry about. I don't want everyone to make a lot of changes just for us, we can keep the kids out of other peoples stuff - it is mainly interacting with other kids who have eaten PB that would worry me. Antibacterial hand wipes will take care of it I just don't know how stressful it will be trying to police in the woods. Also, with the tree nuts I just don't know what they will have a reaction to. At least one of them tested positive for pecan, so I would assume hickory nuts could be a problem. Last time we went hiking we turned around and they were throwing hickory nuts into the stream. We wiped their hands off immediately so no way to tell if they would have a reaction or not.
We will probably ease into it since they have not been camping at all anyway. Backyard -> overnight just family -> camping with small group(a trip like this one would probably be perfect) -> larger outing like GSMTR
