The Duke of Cambridge has described Prince George as "pretty loud and of course extremely good looking" in his first public engagement since the birth of his son.
Speaking at the Anglesey Show in North Wales, Prince William said: "I thought search and rescue duties over Snowdonia were physically and mentally demanding but looking after a three-week-old baby is right up there."
William was also thanked by a teenager he rescued while on duty as a search and rescue helicopter pilot in August last year during the visit.
The Duke of Cambridge came to the aid of Sharon West, 17, when she was caught in a rip tide.
William said he was pleased the 17-year-old made a full recovery, before revealing it was the fastest rescue he had ever completed in just 38 seconds.
Prince William subsequently warned the girl to be "aware of the conditions" next time she goes to the beach.
The Prince confirmed he would be leaving Anglesey and moving "elsewhere" when his RAF posting comes to an end next month.
William said the island of Anglesey had been an "immensely special place" to both him and his wife, the Duchess of Cambridge, during his posting, revealing they both would "miss it terribly".
An announcement on William's future in the military is expected in the coming weeks when his tour is completed.
William watched gundog and falconry displays at the show and met local young farmers before spending around an hour chatting to members of the public.
