The King exercises his authority here as the Head of State. In Belgium, there is a tradition that the King or Queen becomes the godparent whenever a seventh child is born to a family. The family can then request the King (when it’s a boy) or Queen (when it’s a girl) to become their godparent. The godchild will then receive a gift when it’s born, and when the child turns 15, he or she is invited to the Christmas Concert at the palace.
