How can an infant repent?
Does an infant understand sin?
The parents speaks in behalf of the infant since infant are not in an age to know right and wrong. It’s like in the Old Testament when a male child is being circumcise after 7 weeks. Baptism replace circumcision in the New Covenent established by Jesus Christ.
Furthermore, Paul notes that baptism has replaced circumcision (Col. 2:11–12). In that passage, he refers to baptism as “the circumcision of Christ” and “the circumcision made without hands.” Of course, usually only infants were circumcised under the Old Law; circumcision of adults was rare, since there were few converts to Judaism. If Paul meant to exclude infants, he would not have chosen circumcision as a parallel for baptism.
This comparison between who could receive baptism and circumcision is an appropriate one. In the Old Testament, if a man wanted to become a Jew, he had to believe in the God of Israel and be circumcised. In the New Testament, if one wants to become a Christian, one must believe in God and Jesus and be baptized. In the Old Testament, those born into Jewish households could be circumcised in anticipation of the Jewish faith in which they would be raised. Thus in the New Testament, those born in Christian households can be baptized in anticipation of the Christian faith in which they will be raised. The pattern is the same: If one is an adult, one must have faith before receiving the rite of membership; if one is a child too young to have faith, one may be given the rite of membership in the knowledge that one will be raised in the faith. This is the basis of Paul’s reference to baptism as “the circumcision of Christ”—that is, the Christian equivalent of circumcision.
Infant baptism is only the beginning in a child life. Once he reaches the age of reason. He is given the sacrament of Confirmation.
The Catechism states the following confirmation.
1293 In treating the rite of Confirmation, it is fitting to consider the sign of anointing and what it signifies and imprints: a spiritual seal.
Anointing, in Biblical and other ancient symbolism, is rich in meaning: oil is a sign of abundance and joy;103 it cleanses (anointing before and after a bath) and limbers (the anointing of athletes and wrestlers); oil is a sign of healing, since it is soothing to bruises and wounds;104 and it makes radiant with beauty, health, and strength.
1294 Anointing with oil has all these meanings in the sacramental life. The pre-baptismal anointing with the oil of catechumens signifies cleansing and strengthening; the anointing of the sick expresses healing and comfort. The post-baptismal anointing with sacred chrism in Confirmation and ordination is the sign of consecration. By Confirmation Christians, that is, those who are anointed, share more completely in the mission of Jesus Christ and the fullness of the Holy Spirit with which he is filled, so that their lives may give off "the aroma of Christ."105
Of course there are two tradition of annointing. In the Eastern Rite Catholic Churches, baptism, confirmation, and holy communion is given to the infant. The infant is baptized, annointed with chrismation, and received the Blood of Christ in small doses.
