I know I am late but I’ve been busy with school but I would like to know at what point the Triple A team will begin attending the event. Once they start would we be seeing less of other family members?
As far as I know the princes/princesses (in the past & present) start to participate when they reach the age of 18.
In the Netherlands, people from 18 years of age are usually of age, and from 21 years of age they are completely 'independent'.
Article 1: 233 of the Dutch Civil Code states:
Minors are those who have not reached the age of eighteen years and are not married or registered or have been married or registered or with the application of art. 253ha of age have been declared.
Before 1988, people were of age at 21 years old, before 1901 it was even the age of 23 years.
