As part of the Church of England we baptise children, as well as having baptisms for adults.
We appreciate other church traditions’ understanding of baptism as being all about an informed adult decision and their reasons for leaving baptism until a person is old enough to make baptism decisions for themselves. However, we also value the benefits of God’s blessing and spiritual protection following the decisions made on the child’s behalf by parents and godparents. Importantly, we also see a child’s baptism as a beginning of their commitment to God which is confirmed later when, as an adult, they can make their own commitment decisions at a confirmation service. We understand this to be inline with the biblical practice of the church in Acts 8.14-17
14 When the apostles in Jerusalem heard that Samaria had accepted the word of God, they sent Peter and John to Samaria. 15 When they arrived, they prayed for the new believers there that they might receive the Holy Spirit, 16 because the Holy Spirit had not yet come on any of them; they had simply been baptized in the name of the Lord Jesus. 17 Then Peter and John placed their hands on them, and they received the Holy Spirit.
At a confirmation service, a person confirms for themselves the decisions made for them at their christening and a bishop lays hands on them and prays for them to receive the Holy Spirit. Confirmation services are for people old enough to make their own decisions for Christ, and in line with Acts 8.14-17, is part of a process of baptism and laying on of hands for receiving the Holy Spirit. A process, maybe over many years, which begins at baptism and, we hope and pray, comes to completion at confirmation.
