"Please tell me it gets easier," Prince William quipped (via The Telegraph). "Charlotte is very easy, she is sweet. But all the fathers say to me, 'Just you wait, when they get to nine or 11, they get crazy.'"
The doting father added that he is up for the challenge. "I'm looking forward to it. There will be some drama."
While Princess Charlotte doesn't seem to give her parents too much grief, Prince William has admitted in the past that his older son, 2-year-old Prince George, is quite a handful.
During an interview with The Issue in December, the father-of-two joked, "I think George will be extremely bouncy this year because he's suddenly worked out what Christmas is all about ... If I get any sleep on Christmas Eve it'll be good."
Prince William also shared in ITV's documentary, When Ant and Dec Met the Prince: 40 Years of the Prince's Trust, that he's "more emotional" now that he's a parent. "I think, as a father, just because you realize how precious life is and it puts it all in perspective," he said, "the idea of not being around to see your children grow up."
