Kate and the baby are “very well” and “in good form, luckily”, he said, adding: “Sleeping’s going reasonably well so far, so he’s behaving himself which is good news.”
Bookmakers have Arthur as their favourite name, closely ahead of Alexander and James, then Louis, Albert, Philip and Henry, Harry’s proper name.
“Punters are rushing to get their bets on as the excitement builds,” said Harry Aitkenhead of bookmakers Coral.
“Arthur remains the favourite but we’re seeing a lot of money for Albert at the last minute.”
Australia’s representative Alexander Downer asked William: “Have you thought of the name Alexander for him?”
The duke replied: “Well, it’s funny you should say that. It’s a good name.”
George already has Alexander and Louis as his middle names, but the comment sent the odds on Alexander tumbling.
Alex Apati, of bookmaker Ladbrokes, said: “We’re not entirely convinced about this one given that George’s middle name is Alexander, but punters clearly think they’re onto something and we’ve had to respond accordingly.”

Markle is still to announce who will be her maid of honour.
William now has the responsibility of organising a stag party for his brother, as well as performing the best man’s speech.
Bookmakers have Switzerland and the Scottish Highlands as their favourite stag destination. Las Vegas — where Harry was infamously photographed partying naked in 2012 — is considered a remote shot.
“It feels great, a real delight… revenge is sweet” – Prince William on being Harry’s best man. Asked about the name of the royal baby, the Duke of Cambridge says: “I’m working on that.”#5News | #RoyalBaby | @simonvigar5 pic.twitter.com/i5bhrcmwEg
