Yeah, never mind gooey oatmeal, even though it is so good for kids!

on the other hand, I have heard plenty of people getting anaphylaxis from bee stings. Still rare as peanut allergies though.
genetic doesn't mean 100% guarantee that your siblings would get it. it's based on "Genetics Probability of Inheritance" (Punnett Square)
For ie - hearing father + deaf mother (deaf due to genetic) = their child will have a 50% chance of being deaf.
it also depends on if either parent has a recessive gene or not. to answer your question - I don't know if it's genetic or environmental. The only way to answer this question is to get as much family history along with medical history as you can and then show it to experts. I believe Blood Testing (very expensive) can confirm this too.
sourceA theory of the development of peanut allergy has to do with the way peanuts are processed in North America versus other countries, like China and India. Peanuts are widely eaten in China and India, but peanut allergies are almost unheard of there.[citation needed] According to a 2003 study, roasting peanuts, as more commonly done in North America, causes the major peanut allergen Ara h2 to become a stronger inhibitor of the digestive enzyme trypsin, making it more resistant to digestion.[20] Additionally, this allergen has also been shown to protect Ara h1, another major peanut allergen, from digestion—a characteristic further enhanced by roasting.[20]
Another theory, called the hygiene hypothesis, states that a lack of early childhood exposure to infectious agents like germs and parasites could be causing the increase of food allergies.[21]
