Prince Louis, who was born on April 23, was pictured wearing a hand made replica of the Royal Christening Robe which was originally made in 1841 for the christening of Queen Victoria’s eldest daughter.
Louis’ grandparents Prince Charles and his wife Camilla, the Duchess of Cornwall and Carole and Michael Middleton were all present at the London ceremony.
