The Duke of Cambridge and his wife Kate welcomed George Alexander Louis on 22 July 2013.
Wills has now sat down with ITV for a full interview about the challenges of fatherhood and hopes his son will follow in his – and his parents' footsteps – when it comes to charity work.
The interview will air on ITV1 in September.
We have heard William briefly talking about his son already during public appearances, but this will be the first in-depth interview.
This week, the future king told the crowd at the Anglesey County Fair that Prince George was "pretty loud and extremely good looking".
He also admitted caring for a newborn was exhausting, joking: "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 and Kate are currently living with Kate's parents' at the Middleton family home in Bucklebury, Berkshire, but it's thought they will then move into Kensington Palace.
During his appearance in Anglesey yesterday, Prince William suggested that he and Kate will undertake a tour of Australia in the coming year and that little Prince George would hopefully come with them.
