Expert reveals what Kate and William's body language says about their new baby

A body language expert revealed what the royal couple’s gestures meant as they introduced their third baby to the public.

Prince William and Kate Middleton recently revealed their new baby boy to the world as they stepped out of St. Mary’s Hospital from the private Lindo Wing in London.

Judi James, an author, spoke with The Sun and explained the signals given by the Duke and the Duchess of Cambridge through their gestures.

An hour and a half before Middleton went out of the hospital with the third royal baby, Prince William arrived together with his two children, Prince George, four, and Princess Charlotte, two.

The two royal children went to the hospital to meet their baby brother for the first time.

Prince William looked very confident as a brand new father-of-three as he led his kids up the hospital’s steps.

James explained that Prince William’s body language changed as soon as he was joined by Middleton when they made their exit from the building.

"Kate and William's touch and embrace rituals were a lot more openly loving and intimate than usual,” said James.

She also pointed out how Prince William rubbed Middleton’s back when they were standing together on the steps.

Also, James noted how Prince William carried the baby in its carrier using his left hand in order for him to hold Middleton’s hand using his right.

James suggested the gesture tells “a very deep level of affection and empathy.”

In addition, James also took notice of the way Prince William posed on the steps when they first emerged from the building.

She said, "There was a moment when they showed the new baby to the world when William stood slightly away from his wife with his hands clasped across his lower torso in the 'fig leaf' pose.”

The pose supposedly means that it is Prince William’s strong “self-protective barrier gesture.” James explained that it could symbolize that the Duke of Cambridge does not wish to have another baby and that he is contented with being a father to three children.
