MaidOfStars I think perhaps the term should be left to the medical community and not given to the parents.
If something will 100% cause a miscarriage the parents should be told 'we are truly sorry, your baby won't survive past the first trimester because of X' (insert 'placenta won't form, heart won't etc).
For some people it may help but for others it may not.
It is better to give the facts, X does this and so this will happen if it's 100% miscarriage.
I have no reason for my miscarriage.
That has very much hurt and confused me.
I do not know if knowing my baby will ill and that was the reason would help.
I would have a reason so it may be a comfort especially as I blamed myself a lot and wondered why.
Knowing the reason, if it meant when I next ttc there would be things to help and stop miscarriage- it could help.
But perhaps not.
My close friend have 4 miscarriages, at least one was known to be from a genetic problem and that news did not help the parents grief.
They decided to terminate because they were given the details why their baby would not survive, the actual physical issues which meant the baby would die soon.
Sadly after much heartache over the decision it was taken out of their hands before they could go through with it.
My friend always told me that she would rather have no known.
So different people need different things.
Doctors/nurses etc should use the terms between themselves and just explain the situation, not give labels imo.
