Prince Harry and Prince William used to always hang out with each other when they were kids.

In one of their throwback photos, the royal siblings proved how different their personalities are. In the snap, Prince William and Prince Harry are both holding miniature pets in their arms.

Prince William is looking straight into the camera with a serious look on his face. Upon closer inspection, it also seems as though he wasn’t very thrilled to be with Prince Harry at that time.

Prince Harry, on the other hand, showed off his mischievous side in the throwback photo. The Duke of Sussex is glancing at his older brother with a naughty grin on his face.

Growing up, Prince William and Prince Harry couldn’t be more different from one another. The latter was known as the joker of the family, while Prince William was known as the more serious of the two.

The differences between the royal siblings became more evident as they got older. And by the looks it, their different personalities was also greatly influenced by their future roles in the royal family.

Meanwhile, in another throwback photo, Prince William looks dapper in an all-white ensemble with matching pink suspenders. The Duke of Cambridge was just around four or five years old when he served as a page boy for a royal wedding.

In the picture, Prince William isn’t looking straight into the camera. His small face is turned towards his left side. He is also standing in front of a young girl, who served as a bridesmaid at the wedding. The young girl’s face is turned against the camera.

Prince William’s rosy cheeks are highlighted in the photo. And his blonde hair looks even lighter under the heat of the sun. Prince William looks exactly like his only daughter, Princess Charlotte. The dad of three shares the same skin tone and expression with his 4-year-old daughter.
