The father of 2-year-old Prince George and 8-month-old Princess Charlotte opened up about becoming a parent in a new ITV documentary, When Ant and Dec Met the Prince: 40 Years of the Prince's Trust, which airs Monday night in the UK.
"I'm a lot more, um, I'm a lot more emotional that I used to be," the 33-year-old Duke of Cambridge explains. "Yeah, weirdly."
"I never used to really kind of sort of get too wound up or worried about things," he continued. "But now, the smallest little things, I can feel, you well up a little bit more and you get affected by the sort of things that happen around the world or whatever a lot more, I think, as a father, just because you realize how precious life is and it puts it all in perspective, the idea of not being around to see your children grow up."
