Prince William adorably pushed his younger brother, Prince Harry, on the swing while Princess Diana looks on.

In the unearthed video taken when Prince William was roughly around 4 years old and Prince Harry was 2 years old, the late Princess of Wales can be seen spending time with her two sons outdoors.

The mom of two is wearing an all-pink ensemble while sitting on the grass outside the palace. Prince William and Prince Harry are in their matching military uniforms, and they have huge smiles on their faces.

Prince Harry is sitting on the swing while Prince William is pushing him from behind. At one point, Prince William pushes a little too strongly and this seemingly got Princess Diana worried. Prince Charles’ ex-wife stood up and picked up Prince Harry from the swing.

Princess Diana carries Prince Harry in her arms and follows Prince William who is walking in front of them. But instead of going back into the palace, Prince William hides from under the bushes and Princess Diana calls her son’s attention.

Prince William immediately follows Princess Diana’s instructions and runs after his mom and younger brother. Princess Diana picks up Prince Harry’s maroon beret before going inside their home.

Throwback photos and videos of Princess Diana with her sons are being uploaded on social media by royal fans who wish to remember the late royal. The same Instagram user uploaded a snap of Princess Diana teaching Prince William about animals and shapes.

In another photo, Princess Diana is dressed in an all-white ensemble and she also has a tiara on her head. She is standing in between Prince William and Prince Harry who are kneeling in front of her. The young boys are in matching brownish grey suits and khaki pants.

Both Prince William and Prince Harry have smug looks on their faces while Prince William holds on to his mom’s hand. Princess Diana appears to have a fake smile on her face.
