Oh brother! What book are you reading and self interpreting? Matthew 28:16 says nothing of the sort.
From Matthew 28:16-20 Douay-Rheims
16And the eleven disciples went into Galilee, unto the mountain where Jesus had appointed them. 17 And seeing him they adored: but some doubted. 18 And Jesus coming, spoke to them, saying: All power is given to me in heaven and in earth. 19 Going therefore, teach ye all nations; baptizing them in the name of the Father, and of the Son, and of the Holy Ghost. 20 Teaching them to observe all things whatsoever I have commanded you: and behold I am with you all days, even to the consummation of the world.
Admit you're a modernist and move on.This topic has been discussed many times here and the Infant Baptize deniers lose every time.
Teach, make a disciple of, make a pupil, instruct, no infants. Want to try again? Matt. 28:19, 19, yes I hit the 6 instead of 9!!!
In no instance does the N.T. speak of infants being baptized.
