I don't believe the op expects the bereaved mother to modify her behaviour, she is just sharing how she feels about it. She had an instant reaction. It's true there are always triggers, about this and other sorts of things, and eventually we grow thicker skins.
There was no facebook and the like years ago and, for me, it still seems strange that people are willing to put their personal business on show but that's probably an age thing for me. I'm not generally old fashioned, just find this odd but I am a very, very private person.
The issue of losing a child, particularly a still born baby, has been much on my mind over the past week after long talks with a dear friend whom I have known since childhood, whose third, unplanned but much wanted, baby was still born. He was telling me how he remembers sitting outside the room crying while the doctor was talking to his wife. He was pondering that when they are no longer around, there will be nobody to remember the baby; his children were very small when their sibling was born.
I've been thinking about the realities of that ever since. I will write to him later.
It hasn't happened to me so maybe I should not get too involved here. My first instinct was sympathy with how the op felt, we are here to support each other above all.
I'm so sorry for all your losses, mums on here. I am a mother too. x
