I have said for a long time that having a child die is one of the most human experiences (more flagrantly "welcome to being human"). We are fortunate to live in a time where it has become a rarity. Nice to see someone try to put numbers on it.
why do you consider it one if the most human experience?
my interpretation: because it invokes raw emotion and wasn't uncommon.
I think about it this way: until about 3 or 4 generations ago, every single one of my ancestors running back to the time before they were 'human' experienced the loss of a child.
miscarriage is still sadly common, and some of us believe that is a child dying, and it is sad.
