In his first sit-down interview since welcoming new son Prince George, Prince William reflects on how his life has changed since becoming a father.

"I think the last few weeks for me have been just a very different emotional experience," William told CNN's Max Foster.  "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." 

The Duke of Cambridge opened up about how it felt introducing Prince George to the world on the steps of London's Saint Mary's Hospital alongside his wife Kate Middleton. "I think I was on such a high anyway, and so was Catherine, about George, that really we were happy to show him off to whoever wanted to see him," he said. "As any new parent knows, you're only too happy to show off your new child and, you know, proclaim that he is the best looking or the best everything."

Giving an update on Baby George, William called his son "a little bit of a rascal" so far. "So he either reminds me of my brother or me when I was younger. I'm not sure. But, um he's uh, no, he's uh, he's doing very well at the moment. He's... he does like to keep having his nappy changed..." When  asked whether he was first to perform diaper duty, he responded, "I did the first nappy, yeah. Exactly." 

Prince William also spoke about putting the baby into his car seat and driving off himself from the hospital. "Believe me, it wasn't my first time. And I know there's been speculation about that. I had to practice, I really did," he said about the car seat.  "I very much feel if I can do it myself, I want to do it myself. And there are times where you can't do it yourself and the system takes over or it's appropriate to do things differently.  But, I think driving your son and your wife away from hospital was really important to me."

He also said Kate is doing "very well" with her motherly duties and also revealed that the couple's dog Lupo is accepting the new arrival. "He's coping all right, actually. As a lot of people know who have got dogs and bringing newborn back, they take a little bit of time to adapt. But no, he's been all right so far. He's been slobbering sort of around the house a bit, so he's perfectly happy."
