Just after celebrating their fifth wedding anniversary, The Duke and Duchess of Cambridge, William and Kate, are celebrating the first birthday of their second child, Princess Charlotte.
Four photographs have been released by Kensington Palace, taken by the Duchess herself.
In the pictures, one-year-old Charlotte can be seen almost walking, pushing a wooden trolley full of blocks, in a light-pink dress and matching cardigan.
Princess Charlotte was born on May 2, 2015.
"The Duke and Duchess are very happy to be able to share these important family moments and hope that everyone enjoys these lovely photos as much as they do," a Kensington Palace spokesperson said.
