The Kensington Palace shared several new adorable photos of Princess Charlotte on its Twitter account Sunday, ahead of the toddler’s first birthday Monday. The photos come as the princess’ privacy had been carefully safeguarded by the royal family; she has been seen in public only one in the past year, Metro reported.

Princess Charlotte was born on May 2 last year to Prince William and Kate Middleton, and the world media had captured the infant’s photos when the birth announcement was made. She was named Charlotte Elizabeth Diana as a tribute to William's mother, the late Princess Diana, and Queen Elizabeth, who celebrated her 90th birthday on April 21.

The Duke and the Duchess of Cambridge also have a 2-year-old son together, Prince George.
