In October 1927, Leopold and Astrid had a daughter, Princess Joséphine-Charlotte (later Grand Duchess of Luxembourg). The birth of her only daughter had been a tough period for Astrid. One year later, she and her husband visited the Dutch East Indies (now Indonesia). Upon their return from Dutch East Indies, they moved into Stuyvenberg Castle. In September 1930, Astrid gave birth to Prince Baudouin, who eventually became King of the Belgians. She and her family lived at Stuyvenberg, not far away from the Royal Castle of Laeken.
