Prince William teamed up with his brother Prince Harry for a polo match, to raise money for Skillforce and The Royal Marsden Cancer Charity, in Berkshire.
The Duke of Cambridge, who recently became a father, said that being a dad has been all about "nappies, nappies, nappies", and that it was good to get away for the afternoon, Sky News reported.
The Prince also added that as he was 'in baby mode', he was not really 'in the zone' for the polo match.
After scoring the winning goal, Prince William was presented with a mini polo mallet for his nearly two-week-old son, George.
The Duke is supposed to return to work as a search and rescue pilot at RAF Valley in Anglesey, after his two weeks' paternity leave ends.
