The Swedish royals gathered at the Drottningholm Palace Chapel to celebrate Princess Ines' royal christening on Friday.
Princess Sofia, 40, proudly carried her four-month-old daughter as she and her husband, Prince Carl Philip, 46, arrived at the service with their three older sons in tow.
As tradition, Princess Ines wore the royal christening gown, which has been in use since the baptism of Prince Gustaf Adolf, Duke of Västerbotten in 1906.
The day had double celebrations for the couple as they marked their milestone tenth wedding anniversary, after sharing some never-before-seen images from their nuptials.
King Carl XVI Gustaf and Queen Silvia led the rest of the Swedish royals at the service, including Crown Princess Victoria and Prince Daniel with their children, Princess Estelle, 13, and Prince Oscar, nine.
Estelle was one of the five godparents chosen for Princess Ines, alongside some of Prince Carl Philip and Princess Sofia's closest friends.
