In adorable new photos, Britain’s newest prince, Louis, is cuddled by his big sister Princess Charlotte.

Two pictures of the newborn were released by Kensington Palace Sunday.

One photo was taken when Prince Louis was just 3 days old.

In the other, Princess Charlotte plants a kiss on her baby brother’s forehead. It was taken on her third birthday.

A palace statement said Sunday that William and the Kate Middleton, the Duchess of Cambridge, are "very pleased" to share the photos. The photographs were taken by Middleton.

Louis was born at St. Mary’s Hospital in London on April 23, weighing 8 pounds, 7 ounces.

“The Duke and Duchess would like to thank members of the public for their kind messages following the birth of Prince Louis, and for Princess Charlotte’s third birthday,” Kensington Palace tweeted.
