fragment ...marvelous as a new word....
why is there no word, like widow, to describe a mother who has lost a child?
--Marly Swick, A Hole in the Language
marvelous as a new word, my daughter
almost asleep at the breast, her hair curled
over her ear, her soft jaw swirled
with down. Oh, her last fluttering tugs
go deep. Her sleep-flushed cheek,
her upturned ear. For her, I've learned
to name its parts: helix crest,
oval window.

“Finally, the problems that you as a bereaved parent have in getting social support from others can intensify your difficulties. While society values the parent-child relationship above all others, it does little to assist you as breaved parents. There is not even a word to identify you, such as the term orphan for a child who has lost its parents or the term widow or widower for one who loses a spouse.
There are greater social problems in responding to the death of a child than to other deaths. This is because as a bereaved parent you represent the very worst fears of every parent. If it happened to your child, then it could happen to my child. As a result, bereaved parents are avoided more than most other mourners and are victims of social ostracism and unrealistic expectations. This is why so many report that they feel like social lepers.
