Prince William dubbed Kate Middleton's 'fourth child' as cracks in marriage surface

Prince William has been called out for habitually throwing "tantrums" with his wife Kate Middleton having to treat him like "a fourth child".

Royal author, Tom Quinn, spoke to Express and shared that the Duke and Duchess of Cambridge  have the tendency to sort things out humanely despite their fights being troublesome. 

"Kate treats him [William] like the fourth child because he's prone to tantrums," Quinn said. 

"They do have rows. It's not a perfect marriage. They have terrific rows.

"But, where some couples have a row and throw heavy vases at each other, William and Kate throw cushions at each other. It's always kept under control."
