In my tradition we practice “believers baptism” which occurs whenever the individual child realizes his/her need for a Savior and makes a conscious decision to follow Christ. This happens at different ages for different individuals and is referred to as the age of reason or accountability.
With infant baptism I understand the reasoning to be that the infant is brought into the church by baptism and then in order for a walk of faith to be effectual the child must confirm their faith at the age of reason. In your church, does this happen when the individual child realizes they want to confirm or is the more common practice to hold Confirmation at a certain age for all children?
From the Catholic Catechism
1250 Born with a fallen human nature and tainted by original sin, children also have need of the new birth in Baptism to be freed from the power of darkness and brought into the realm of the freedom of the children of God, to which all men are called. The sheer gratuitousness of the grace of salvation is particularly manifest in infant Baptism. The Church and the parents would deny a child the priceless grace of becoming a child of God were they not to confer Baptism shortly after birth.
1257 The Lord himself affirms that Baptism is necessary for salvation. He also commands his disciples to proclaim the Gospel to all nations and to baptize them. Baptism is necessary for salvation for those to whom the Gospel has been proclaimed and who have had the possibility of asking for this sacrament. The Church does not know of any means other than Baptism that assures entry into eternal beatitude; this is why she takes care not to neglect the mission she has received from the Lord to see that all who can be baptized are “reborn of water and the Spirit.” God has bound salvation to the sacrament of Baptism, but he himself is not bound by his sacraments.
1252 The practice of infant Baptism is an immemorial tradition of the Church. There is explicit testimony to this practice from the second century on, and it is quite possible that, from the beginning of the apostolic preaching, when whole “households” received baptism, infants may also have been baptized.
SUMMATION
Birth is regulated by GOD [not every act of married intercourse results in a pregnancy]
At the INSTANT of birth GOD implants a Soul
Depriving infants of baptism is Unbiblical:
John 3:5 [5] Jesus answered: Amen, amen I say to thee, unless a {ANY / ALL implied here; & NO mention of age] man be born again of water and the Holy Ghost,** he cannot enter into the kingdom of God."**
It puts into danger the very soul of the infant, who would spend eternity outside of heaven; but NOT in hell, should they die before age of reason.
