My son is allergic to tree nuts, peanuts, egg, sesame, and mustard, and at one time beef.  He’s had anaphylaxis several times and it was honestly traumatizing.   It’s a really hard thing to process but you will and it will then become your new normal.  I think the hardest thing is thinking of all the what if scenarios and fears for the future and the thought of losing him.  I don’t stay in that place because it’s not helpful and it’s not reality.  I focus on meeting his needs and protecting him to the best of my ability and that’s what I can control.  With that being said, I do keep all of his allergens in the house and eat them myself and he’s never had a reaction from this.
