The Duke of Cambridge has revealed he is not planning to have another baby with his wife at the moment as "one's enough".
William was quizzed about a little brother or sister for son George when he visited the Irish Guards at their military base in Aldershot with wife Kate to mark St Patrick's Day.
The proud royal father, who is the regiment's Colonel, said during their day with the soldiers and officers that George – who will be joining them on their trip to New Zealand and Australia next month – was now crawling.
The Duchess presented sprigs of shamrock to around 300 soldiers on parade and honoured the regimental mascot, Irish Wolfhound Domhnall, with his own bunch of the well-known plant.
Former Regimental Sergeant Major Ray Collister (56), from Tamworth, lost no time in asking William if he was planning to add to his family after the ceremony.
The Duke replied: "Maybe one day; one's enough at the moment."
In keeping with the day, the Duchess wore a stylish emerald green coat by Hobbs and matching hat by Gina Foster, and wore a gold Cartier Irish Guards brooch, a royal family heirloom also worn by the Queen Mother.
At the start of the ceremony William was one of the first to receive a shamrock from his wife and, following tradition, tucked it under the regimental star on the front of his cap.
Before the royal couple were around 300 soldiers – the majority from the Irish Guards, but they were joined on parade by a company of reserve soldiers from the London Regiment, with whom they are paired under the new Army2020 restructuring process.
The event is the one day when the entire regimental family comes together and there were veterans on the parade ground proudly displaying their medals and a small contingent of cadets.
Kate, who wore a large shamrock sprig on her left shoulder, presented baskets of the plant to officers and warrant officers, who handed them out to the soldiers.
After the presentation of the shamrocks, the royal couple went to the cookhouse, where dozens of guardsmen were sitting down to lunch. They accepted a toast in their honour, with the Duke and Duchess drinking port while most of the servicemen downed Guinness and Fosters lager.
During the visit, William also chatted to Ray Kidd (72), a former regimental cook, who said: "I asked him if he'd bring George next time and he said, 'Yes, that's a good idea. I'll get him fitted for a uniform'."
