Growing up as royalty can be complicated.

Body language expert Darren Stanton attests that Prince William's childhood was, and experts believe the Duke of Cambridge is now trying to offset those difficulties with his own children.

This Sunday, ahead of Father's Day in the United States and the United Kingdom, Stanton analyzed the attitudes of three of the most famous royal fathers toward parenting. First, Prince William.

"Prince William is definitely not averse to being seen by the media first and foremost as a father and husband, rather than as a future monarch," Stanton told Marie Claire on behalf of Slingo (opens in new tab).

"From his interactions with him, Kate, and their children, it is clear that he wants to be a hands-on, 100 percent devoted father. [For example, he kneels down to the height of his children during engagement and makes eye contact, a classic way to build trust and connection.

Stanton does not believe that Prince Charles is a bad father by any means, but believes that he has become more comfortable and confident when interacting with his sons (although, of course, Prince Harry's departure from royal life has added another layer of complexity).

"I think Prince Charles, in particular, has evolved as the decades have gone by and has become more comfortable in his role as a father," says the expert.

"Historical footage of Prince Charles when William and Harry were young shows that he tended to be less hands-on, leaving it to Princess Diana and her staff to take care of the children at royal functions.

"But what is clear now is that Prince Charles loves Harry and William very much. I think it is clear from the way Prince Charles treats Harry when they are together that he is still a very loving father."

According to Stanton, Prince Charles is also a thriving grandfather of five.

"Prince Charles has also become much more docile, seems to have developed a sense of touch, and is more willing to show public displays of affection, such as hugs and kisses," he says.

"When Prince Louis became too restless with his parents during the Jubilee celebrations, we definitely saw a softer side of him as he fully embraced his position as grandfather while caring for Prince Louis."

As for the Duke of Sussex, Stanton sees parallels between the way he parented Archie and Lili and the way his brother treated George, Charlotte, and Louis.

"Prince Harry, on the other hand, is very similar to William, and although we rarely catch glimpses of Archie and Lilibet, it is clear that he is not afraid to be seen playing with the children in public and is enamored of them," says Stanton.

"Both royal children, thanks to their close relationship with their respective fathers, William and Harry, are going to have a very different relationship with their parents than the royal family had a few years ago."
