Prince William is one proud poppa and he couldn't help gushing about the joys and surprises of fatherhood in an interview with CNN. In his first interview since the royal baby was born, the Duke of Cambridge opened up about bringing Prince George home, changing nappies, how Catherine is adjusting and the legacy he wants to leave behind for the little baby.

"He's a little bit of a rascal," Prince William said. "I'll put it this way, so he either reminds me of my brother [Prince Harry] or me when I was younger, I'm not sure."

"But he's doing well at the moment," he continued. "He does like to keep having his nappy changed."

He said that he did his first diaper change already and described the experience as "nerve-wracking," the Daily Mail reports. As far as his wife Kate Middleton, Prince William said she is adjusting fine to motherhood admitting that she does have to get up quite a bit throughout the night.

"He [Prince George] kind of wriggles around quite a lot. And he doesn't want to go to sleep that much, which is a little bit of a problem," he said.

When asked if he gets up to tend to the baby he said yes but not as much as his wife.

"A little bit. Not as much as Catherine. But, you know, she's doing a fantastic job [she's doing] very well," he said.

Prince George was born on July 22 and left St. Mary's Hospital the following day. According to the Daily Mail, the Duke said of introducing his son to the world for the first time that the new parents were excited to show off the baby and he was glad the world wanted to see his son but overall he is enjoying his responsibility.

"I think the last few weeks for me have been just a very different emotional experience. Something I never thought I would feel myself. And I find, again it's only been a short period, but a lot of things affect me differently now," he said.

"For me, Catherine, and now little George are my priorities," he continued. "And Lupo."
