Touching piece. My parents lost their daughter 15 years ago. Losing my sister was overwhelming for me, yet seeing my parents in such excruciating emotional pain compounded it. They've both passed away since, but a part of them died the day their daughter died.
Yes, my Godparents lost a child years ago - they aged at least 15 years over night.
It is past all understanding that, historically, most people lost half? most? of the children born to them.
