In an interview with CNN for Prince William's Passion: New Hope, New Father, Wills talks openly about life as a new father, describing the last couple of weeks as an 'emotional time'.
"I think the last few weeks for me have been just a very different emotional experience. Something I never thought I would feel myself," he said.
He also spoke about the daunting moment he left hospital with Kate and George, saying: "I think more shock and dauntingness [sic] was the feeling I felt. 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.
"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."
However when asked if he was comfortable with all the media attention, he said: "Again it's not somewhere I enjoy being, but I know that the position I'm in... that's what's required of me to do.
"It's nice that people want to see George, so, you know - I'm just glad he wasn't screaming his head off the whole way through!"
And remember that smooth car seat fitting? He had a lot of dry runs!
William also spoke about his desire to be as independent as possible, given his position as a senior member of the Royal family:
"Well, where I can be I am as independent as, as I want to be. And same as Catherine and Harry. We've all grown up differently to other generations. And 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. And I don't like fuss so it's much easier to just do it yourself."
The new dad also described his son as a bit of a 'rascal', saying: "He's a little bit of a rascal, put it that way. So he either reminds me of my brother or me when I was younger. I'm not sure.
"But he's doing very well at the moment. He does like to keep having his nappy changed. He's growing quite quickly actually. But he's a little fighter. He wriggles around quite a lot. And he doesn't want to go to sleep that much, which is a little bit of a problem! Catherine is doing a fantastic job."
William was giving the interview as part of his work to protect wildlife in Africa. Kate will attend her first public engagement since George's birth on September 12 when she accompanies William to an event for the charity Tusk Trust.
The proud new dad is now back at work in Wales, and Kate and George have also joined him at the cottage they share on Anglesey.
The full interview will be broadcast on CNN internationally on September 15.
