There’s a pretty good theory about that: that thanks to kids being more sheltered these days, with parents overdoing it with antibacterial soap, and wipes and hand cleanser that kids immune systems aren’t developing properly.
So, not having anything to work against, the immune systems find stuff to attack. Like peanut products.
Parents are realizing that 60 million children have been murdered in abortuaries in the past four decades. As a result, parents have begun to treat children like an endangered specie.
On the rare occasions that children are allowed outside to play, they do so under the close supervision of adults, they are slathered in sunscreen and covered head-to-toe in helmets and protective padding. When I was a kid everyone was a little jealous when another kid showed up with a cast on his arm or leg, now everyone would be kept away from the kid with the cast because everyone suspects his parents are abusive.
If children were anywhere near as fragile as modern parents think, humanity would have been extinct before we even learned how to make fire.
