I was taught Purgatory was for children? I don’t know why but it was not a bad place but a place for a soul that was too young to go to heaven or hell. I know I sound like a nut I must ask my mom tomorrow.
As I recall; unbaptized babies/children would go to "Limbo." They would be content but never see God.
The modern Church has quietly repealed that belief. The official statement was that "God bound Salvation to Baptism, however he, himself, is not bound by his sacraments."
