These things are tricksy. On the one hand, kids do live in a world far more magical than we (usually) do as adults, and they don't always think with the same sort of logic. As an example, there was an incident when I was around 5 years old.
I knew perfectly well not to eat anything I found on the ground, but one day I saw some lovely moist brown sugar lying there so enticingly, just waiting for me, clearly wanting to be tasted. And somewhere in my little mind I knew it was really just fine damp sand in the ditch where rain had caused it to settle, but I thought it could be brown sugar. It looked exactly like brown sugar. It might be brown sugar! So of course I tasted it. Yuck. I learned quickly that it wasn't any kind of sugar at all, but that didn't stop me from growing up healthy and a little wiser.
The world lost a tiny bit of its magic for me that day, but I'd hope that we can keep our adult selves from preemptively removing too much magic too soon just to keep kids safe from all the things that could happen but very likely never will.
