My DH and I don't have food allergies--our daughter does though. But we are the lone family in our extended family (cousins, nieces/nephews, etc) that have food allergies. Also out of all of our friends and their young kids, we don't have any friends with food allergies either.
I feel like we are the only ones around that deal with food allergies. I know we aren't because I am a teacher and some of my students have them--but in our circle of family and friends no one else has food allergies.
It is super frustrating sometimes.
