“He came to save all through himself; all, I say, who through him are reborn in God: infants, and children, and youths, and old men.

“Baptize first the children, and if they can speak for themselves let them do so. Otherwise, let their parents or other relatives speak for them” (The Apostolic Tradition 21:16 ).
Even Zwingli allowed infant baptism.
