CA Peanut Allergy

So some of you know that CA hates peanuts and peanut butter. Always has. Well, a couple of weeks ago he accidentally ate 1/2 a peanut butter cookie and actually had an allergic reaction -throwing up, bloodshot eyes, red face, wheezing and coughing. Fortunately, we were able to give him Benadryl and it cleared up. No rush to the ER. Unfortunately, it seems everytime he eats peanuts, his reactions are escalating.
We saw his doctor today and she prescribed an Epi pen to be carried with him. This is in case he has a life threatening reaction. If you ever have to give it to him, he would also need to go to the ER right away as the Epinephrine only lasts for a few minutes in some people.
Anyway, she advised us to be a peanut free house. Which is going to be very difficult for us. No more peanut butter sandwiches, butterfingers, Nutter Butters, and most importantly I am not sure about the status of making peanut butter cups at Christmas. All of this is sort of drastic, but if the allergy is escalating, of course we want to be cautious.
So I am just putting this info out there for those who will be watching him. We will have the Epi pen with him somehow and just be cautious about anything that might have peanuts in it or peanut oil or even be careful of things processed in places that use peanuts.
He is going to have a blood test soon to determine if he is allergic to other types of nuts so we will keep you posted.
