Prince William and Catherine support one another during those difficult times, he told BBC documentary on mental health.
The program is focusing on men’s mental health and football and is going to be hosted by former professional footballer Marvin Sordell.
“Having children is the biggest life-changing moment, it really is. And there’s no one there to, kind of, help you, and I definitely found it very, at times, overwhelming,” the Prince added.
The Princes is father to Prince George, 6, Princess Charlotte, 5, and Prince Louis, 2.
Prince William said that emotions can “come out of the blue” which you do not expect or think you have already dealt with.
