Sweden’s youngest royal prince, His Royal Highness Prince Alexander Erik Hubertus Bertil was baptized in a beautiful ceremony in Stockholm Friday.
His parents, Princess Sofia, 31, and Prince Carl Philip, 37, looked picture-perfect at the event held at Stockholm’s Drottningholm Royal Palace Chapel on Friday.
The tiny royal stayed perfectly collected during the ceremony, not even shedding a tear as Archbishop Antje Jackelén poured water on his head.
Prince Alexander’s cousins, 4-year-old Princess Estelle and 2-year-old Princess Leon were also in attendance, along with Prince Oscar, 6 months, and Princess Estelle, 4.
Photos from inside the church show Prince Oscar and Prince Alexander playing with each other during the service.
PEOPLE reports Prince Alexander wrote the family’s heirloom christening gown. As per tradition, Alexander’s name was embroidered into the lining of the satin silk heirloom alongside the names of those who wore it before them.
