Princess Catharina-Amalia was enrolled in Bloemcamp school in Wassenaar on 10 December 2007. Her birthdays are usually celebrated with a concert at Kloosterkerk, The Hague. The concerts are attended by ambassadors and members of the royal household and the Council of State of the Netherlands. On her seventh birthday, a Douglas C-47 Skytrain once owned by her great-grandfather, Prince Bernhard of Lippe-Biesterfeld, was named after Catharina-Amalia by Peter Hartman. The princess herself did not go to the naming ceremony because of school obligations.
