Wouldn't worry about if someone flicked water on your head as a baby or not its not Biblical, Christ came to rescue man from sin not to condemn little babies who were not flicked with water by pedophiles in weird pagan rituals.

None of that stuff does anything its all ceremony and traditions of man, its man based works its not at all scriptural,

The Priest dunks an incense into the water and says something mysterious in Latin, because its the continuation of the mystery rights from Babylon,

If you had read "Foxes Book of Martyrs" it goes through all the pagan antiquity's that made it into your church, The water itself doesn't have any benefits but the pagan peoples demanded that they keep their customs so today they remain.

When Someone Chooses to be Baptized they are Symbolically saying they are Now Dead to their former Sins and want to be reborn into Christs Righteousness, Then the Devil usually attacks their family strongly and that persons faith will go through many tests or distractions.

When Christ was Baptized by John The Baptists, a Prophet and His Cousin, John Didn't recognize Christ as His Cousin but He saw in Jesus the anti-typical fulfillment for the type of spotless/sinless lamb used symbolically in their sacrificial System to atone for mans Sin.

"The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world." John 1:29

"And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him.
And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost. And I saw, and bare record that this is the Son of God." John 1:31-34

"And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased." Matthew 3:17

I believe being Baptized/reborn into Christ is an Adults Decision, an infant is incapable of making any real spiritual decisions
