This may well be their only photo where they can see their much loved baby's face. Because if they died at only a day old, the odds are pretty high that any photos of them living are with a breathing tube in their mouth, a NG tube up their nose, tape across their face...well, you get the idea. They are going through hell, so anything that makes that even the tiniest bit better is fine with me.
But just think. Think of all they have lost. They haven't just lost all the future years of time together. They have even lost most of the ordinary little joys of that one day. If, as is very likely, their baby was born extremely sick:
No happy first skin to skin - whisked onto a resuscitaire to be worked on by the team
No guess the weight - someone will have seized a moment to convert the SCBU kg to lbs and oz, but they won't have been there to see it
Not "Is it a boy or a girl?" but rather "Why aren't they crying? Are they okay?!?!?"
Not "Great news" phonecalls of delight to the world, but desperate strained calls of despair
No "congratulations" as noone knows what to say
No feeds, no nappy changes, no cuddles...except that wonderful, terrible, one and only last cuddle as the machines are switched off
So, for me, if they want to snatch one nanosecond of normality by sharing the photo they have, then that is fine by me. And if I knew them even slightly, I would be finding something to say about how beautiful their baby was. Because to them, they certainly were.
