His elder sister Ingrid attends the same school and Marius, Mette-Marit's boy, from a previous relationship was also a pupil.
Queen Sonja, known for playing an active role in her grandchildren's life, didn't want to miss the big event and also escorted the five-year-old to meet his new friends.
Meanwhile, in Belgium, the future king and queen, beamed with happiness as they took their brood to begin classes.
