“The newborn Prince will be named Balthasar Felix Karl. He weighs 3,220 kg and measures 50 cm. Prince Balthasar and Princess Claire are in perfect health,” the statement continued.

Balthasar joins big sister Princess Amalia, 9, and big brother Prince Liam, 7. Claire and Félix, who have been married since 2013, became parents in 2014 with the birth of their daughter Amalia. Their second child, Prince Liam, was born in 2016.

It was announced last July that the royal family was growing. “Their Royal Highnesses The Grand Duke and The Grand Duchess of Luxembourg are very pleased to announce that Prince Félix and Princess Claire are expecting Their third child,” the Grand Ducal Court said at the time. “Both families join in their children’s joy.”

Prince Balthasar won’t be the youngest member of Luxembourg’s royal family for long. Prince Félix’s younger sister Princess Alexandra is expecting her first child with her husband Nicolas Bagory. The royal baby is due in the spring.
