This is my impression too. Are there any photographers in Western Europe specialized on this? Working on this subject seems rather accidential to me. Or restricted to some art project.
But I see, Steven's topic is restricted on discussing own family matters.
There was (and may still be) a photographic charity here in Australia which offered a free photographic service for mothers of still born children to have their portrait taken as a memory for the mother of child but the details as to what they provided i don't know.
