Prince William Talks Nappies And Fatherhood

Prince William talks for first time about nappies and fatherhood - and says baby George is a wriggler

Prince William has talked about his first days of fatherhood as he made his first public appearance since the birth of baby Prince George.

After playing in a charity polo match he admitted he would be picking up nappies on his way home – and described baby Georgie as a wriggler!

William took a break from parenting duties to play in the Audi Polo Challenge at Coworth Park, Ascot, Berkshire on Saturday alongside his brother Prince Harry.

The 31-year-old, who scored the winning goal for his team, was presented with a mini polo stick for Prince George by Audi UK director Martin Sander after the match.

William jokingly asked if it was nappies, saying: "I've got to pick some up on my way home."

He admitted it was 'good to get out of the house' for an afternoon but added: "I've got to make sure I'm not too late back."

Of his performance on the pitch, William admitted: "I was in baby mode out there, thinking about nappies, I wasn't really in the zone."

And asked about son George, who was born on July 22, he said: "He likes to move around a lot, he wriggles a lot, he keeps us on our toes."

The Audi Polo Challenge is held each year and this year was in aid of charities SkillForce and The Royal Marsden Cancer Charity, of which William is patron and president respectively.

Kate attended last year's match to support William and Harry, but there was no sign of her on Saturday. She is thought to be at her parents' home in Bucklebury, Berkshire with Prince George.

On Friday, Kensington Palace announced that the birth of the third-in-line to the throne had been formally registered after a registrar from Westminster City Council visited the palace.

William, 31, signed the birth register entry for his son, listing his and wife Kate's jobs as prince and princess of the United Kingdom.
