That never happened. Catholic hospitals don’t do routine baptisms on newborns. They baptize babies in church, then have a little paty.
As I sais, this was a Catholic hospital run by nuns and priests were present visiting patients throughout.
Perhaps this isn't done today, as I know the church has changed greatly since the sixties. I assume that you are both Catholic and have something to do with hospitals, since you seem to be knowledgable as to their practices.
What I don't know is your age and whether you are old enough to have been adult when my babies were born to have knowledge as to what was practiced.
