Baby Sussex's name is Archie Harrison Mountbatten-Windsor. Their son was born on May 6.

The apple doesn't fall too far from the tree.

"#archieharrison is his father's twin," wrote an excited fan.

"The resemblance is out of this world," said another.

One person even got confused over the photos -- “Thought these pictures were of the same child!!”
