I'm still slightly allergic to cats. Doc got that correct. But I've had cats in my house, sleeping on my bed, for decades without hospitalization.
I was allergic to cow milk, and anything remotely containing it. Eczema. Notice the 'was'. Baby suits with hands binded unable to scratch because eczema is an urge to scratch and itch. Arms wrapped in bandages from at the exact hospital cited in the article. Wrapped and re-wrapped every day.
Until I was 8. And then, it just stopped. So today I enjoy milk and cheese, especially cheese.
Being diagnosed is fine, it is a precaution. Actually suffering those symptoms is different. Please don't be do flippant.
Well duh!
If you have a serious allergy, you avoid peanuts like the plague. But if it's minor... say a slight rash being the only symptom... then perhaps it's worth giving the child peanuts, starting with a very tiny amount, and then increasing gradually. Keep an epi-pen around at all times just in case, and if there's a serious attack... drop the attempt altogether and surrender to the fact that your childs quality of life will be less-than-optimal forever more.
Just stop right there.
