I was first diagnosed at age of 2 confirmed to peanut. I was born with eczema and so they warned my parents I may have a food allergy and to avoid peanuts, at the age of 2 my dad unknowingly gave me a peanut butter cookie and that’s the only time I’ve eaten my life threatening allergen. I’ve avoided ever since and got official testing done as an adult where I’m off the charts to peanut and went into a anaphylaxis at the allergist to the peanut test.
We didn’t use any resources, when I was little it was the early 90s, we didn’t even have computers! Haha. There really weren’t any book or any other resources, either, at this time.
