Mrs. Santorum is/was a neonatal nurse.
The baby lived for a short time, they (Mr and Mrs.) held him until he passed, if the kids had been older they would have been there, because they were younger they took the baby home so the kids could say good bye to their brother and the Santorums held a private funeral service for their passed child.
I find nothing creepy about that.
We view our parents and friend who have passed, why not a child.
I stated “if as reported”.
