Council of Florence Session 11 (Bull Cantate Domino): "With regard to children, since the danger of death is often present and the only remedy available to them is the sacrament of baptism by which they are snatched away from the dominion of the devil and adopted as children of God, it admonishes that sacred baptism is not to be deferred for forty or eighty days or any other period of time"
Council of Florence Session 6 "...the souls of those who depart this life in actual mortal sin, or in original sin alone, go down straight away to hell to be punished, but with unequal pains."

Catholic Encyclopedia: Hell: "However, in the New Testament the term Gehenna is used more frequently in preference to hades, as a name for the place of punishment of the damned.[...] held in abomination by the Jews, who, accordingly, used the name of this valley to designate the abode of the damned (Targ. Jon., Gen., iii, 24; Henoch, c. xxvi). And Christ adopted this usage of the term." Jewish Encyclopedia: Gehenna: Sin and Merit: "It is frequently said that certain sins will lead man into Gehenna. The name "Gehenna" itself is explained to mean that unchastity will lead to Gehenna (; 'Er. 19a); so also will adultery, idolatry, pride, mockery, hypocrisy, anger, etc. (Soṭah 4b, 41b; Ta'an. 5a; B. B. 10b, 78b; 'Ab. Zarah 18b; Ned. 22a)."
