Children who have been baptised as babies make their own public commitment to grow in faith in a ceremony called confirmation.
About once a year, the bishop comes to the parish to administer the sacrament of confirmation. Children should be at least 9 years old and must attend preparation classes. After being confirmed, children start to receive Holy Communion at Mass
Adults who wish to be baptised are normally confirmed as well (either on the same occasion, or shortly after their baptism). There is no upper age limit. Adults must attend a series of preparation classes. After confirmation adults are admitted to Holy Communion.
Confirmation, along with baptism, is a sacrament of initiation.
