Prince George is days away from his first birthday and he is already "charging around and opening doors", according to his doting dad, Prince William.
The Duke of Cambridge shared the insight into family life at Apartment 1A in Kensington Palace on Wednesday as he chatted to crowds on a solo visit to Coventry's War Memorial Park.
According to Gill Naylor, the Head teacher of Earlsdon Primary School, one of several schools who came to see William, the popular royal also joked: "I think George will be running faster than me very soon."

Naturally, the crowd was excited to hear about Prince George as he approaches his first landmark birthday on 22 July.
So when William, 32, met sisters Mavis Jarvis, 74, and Mary Jarvis, 72, from Leicester, the first thing they asked him about was his bouncing boy.
Mavis said: "We asked him straight away about the baby and he said it's his birthday next week.
"He said George is charging around and opens doors," she said before adding that the proud royal said of his son: "he's lovely."
The proud father was also inundated with birthday gifts for George, including a handmade card and a plaque spelling his name in scrabble letters. He was also presented with a turquoise and black "loom band" - the latest craze among schoolchildren.
In a pre-released message for the visit to launch the Centenary Fields Project, which aims to protect green spaces around the country by building war memorials, William revealed that being a father has made him value green spaces for the freedom they give children.
He wrote: "As someone who has always enjoyed sport, and now as a new father, I appreciate the importance of allowing our children the freedom to experience outdoor space.
"And not just children - adults benefit just as much, for a stroll, to walk the dog, to exercise or just to get some fresh air.
"Outdoor space is more than a nice-to-have for every community - it is an inalienable part of living well."
