Lots of children died from all sorts of accidents in the old west. I’m sure a few Pueblo tots did fall off cliffs. Children were trampled by horses and other livestock, drowned, got snake bit, got rabies from being bitten by dogs or wild animals, somehow the species has survived. How did prehistoric mothers keep their children safe from Sabre Toothed tigers and Dire Wolves?
I got lost in the Arroyos in Sante Fe New Mexico when I was 4 years old.
Went out exploring when my mother was in the shower and ended up on a steep, narrow foot path on the edge of a cliff in the mountains listening to Bobcats screaming. Obviously I was found, hours later, scared and dehydrated but I survived.
