The Church of England describes this service in the following way:
The birth or adoption of a child is a cause for celebration. Many people are overcome by a sense of awe at the creation of new life and want to express their thanks to God. This service provides an opportunity for parents and families to give thanks for the birth or adoption of a child and to pray for family life. It may be a private celebration at home or in hospital, or it may be a public celebration in church, sometimes with a number of children.
This service is not the same as Baptism (sometimes called Christening), which is the sacrament of initiation into membership of the Church, the Body of Christ.
