Baby rn,
Glad to see you back, and am intrigued by your question.
I've heard of many children who remember their deaths, and the process of returning, but not too much about the interim between death and rebirth. I do recall a case of a boy who said that when he was in heaven he helped people who died in car accidents, because sometimes they didn't know they had died! That was a surprise to me, since he remembered a specific task or activity he had in the afterlife.
I've heard some reports of children who remember seeing angels, Jesus, or deceased grandparents in the afterlife. And many of these kids didn't go to Sunday school, or have any kind of religious training. The parents were surprised that they saw specific beings, and referred to Jesus.
There does seem to be a number of children who say they came back with the assistance of a grandparent who died before the child was born. Some point to photographs of a deceased grandparent and identify them by name, and say they met before the child was born--in heaven. There may even by a book by Elisabeth Hallett about the grandparent connection, since she found this too in her research of pre-birth communication.
It's fairly common for children to tell their parents that they chose them before birth. The kids are usually excited when they inform their parents that they chose them.
Anyone else remember any other posts from the Forum about heaven and the period before rebirth?
