"Looks like Archie is a ginger," one person commented, with others agreeing they could see Prince Harry's looks in his first born.
Others, however, pointed out the resemblance to his mother.
"He's such a cutie!!! Looks a lot like Meghan too," someone commented.
The photos shared today mark the first time the public has got a clear view of Archie's face.
"The Duke and Duchess of Sussex are overjoyed to share the happiness of this day, and would like to thank everyone around the world for their ongoing support," a spokesperson for the royal couple said.
"They feel so fortunate to have enjoyed this special moment with family and Archie's godparents."
