When A Child Dies

I will give you words, show you words.
Every time a child dies, we roll out the comforting memes that "there is no word for a parent who has lost their child." It's a lovely sentiment, one designed to comfort the parent, to show our empathy for the depth of their loss.
And yet, this is easy, lazy. The fact that parents lose their children is as old as humanity. My own family tree is peppered with children who died too soon, including an aunt and a cousin. And still the same old platitudes are brought out, that "there is no word". Well, why not?
There already is a word for parents whose child is stillborn, though it's not in general usage. The word is "stillparent".   By extension, one is a "stillmother" or "stillfather". And with due respect to those who have lost their children at childbirth, I think the same can apply to those who have lost a child later in life. "Still" in the sense of quietness and emptiness, the hole in their lives that is left when a child dies. And "still" in the sense that they will always be the parent of the child who was lost. Perhaps in due time they will come to move on with their lives, but the life of the lost child will forever be a part of them.
