The catechism of Pope St. Pius X says that infants cannot be saved without Baptism. Also, the Baltimore catechism says:
“Think, then, what a terrible crime it is to willfully allow anyone to die without Baptism, or to deprive a little child of life before it can be baptized! Suppose all the members of a family but one little infant have been baptized; when the Day of Judgment comes, while all the other members of a family-father, mother, and children-may go into Heaven, that little one will have to remain out; that little brother or sister will be separated from its family forever, and never, never see God or Heaven. How heartless and cruel, then, must a person be who would deprive that little infant of happiness for all eternity-just that its mother or someone else might have a little less trouble or suffering here upon earth…”
