My little boy has a peanut allergy. He had a reaction the first time he had a tiny bit at age 1 1/2. I know some kids take more than one exposure to have a reaction.
I do not know why you say that her chance of surving to adulthood is not good just because she has a food allergy. My little boy was given peanut butter at his preschool when he was three and the staff their was afraid to use the epipen. Eventually one teacher used it and by the time I got him to the hopsital he was fine. Food allergies are in no way a death sentence.
Honestly I do what the doctor's say and would never try to have him "get over" the allergy by slowly given him what could hurt hime. I think following the doctor's advice and watching what your daughter eats is proactive.
What level is her reaction? EJ is a 2 so he has hopes of growing out of it. So many kids have food allergies now that you are not alone and schools and other parents are used to dealing with them. Also as your daughter gets older she will enjoy telling everyone she can't eat peanuts I know my four year old does. He asks if there are peanuts in everything.
Dealing with a food allergy is a pain but there are so many things that are worse. I consider EJ a happy healthy guy.
BTW our new doctor told us to always carry two epipens because they have a high failure rate. I had never heard that before.
