Child of record
A child of record is a child (born to members or converts to the Church) who has not yet reached the age of 9. While the blessing of infants is not a saving ordinance and is not recorded on the Church's records, it is often used as the trigger for recording a birth and creating the new membership record for the child.
It is not necessary to have a child blessing to create a new child of record. This can be done for older children under 8 years of age at the request of the parents.
The child becomes an official member of the Church when he or she is baptized.
