Robert de Niro recently made headlines by announcing the arrival of his latest child, at the age of 79, signalling his membership to the club of later-in-life famous fathers.

Among them was Charlie Chaplin, who had his eleventh child, Christopher, at 73, and Pablo Picasso who had his fourth child, Paloma, at 67.

With six children from previous marriages already, de Niro ignited a conversation about whether certain ages are "too old" for parenthood or are norms shifting?

Alex Kane, columnist and former director of communications for the Ulster Unionist Party, joined Drivetime to discuss the pros and cons of being an older parent. Kane himself became a new dad six years ago at the age of 62.

He told Drivetime that he was adopted at six years old by parents who were both middle aged, so he "didn't understand the concept of young parents, I knew the concept of two parents irrespective of age who just loved me and saved me from the misery of an orphanage".

He added that when he had his children there were comments on his age being "a bit old".

"If you lived your life on that basis", he said, "thinking you can only be a parent when you're young and one you reach a certain age you won't be able to look after them or you'll forget who they are, you won't be able to recognise them, nobody would ever do anything."

Rather than slowing him down, Kane says that becoming a dad later in life has led to growth. "If I hadn't been an older dad I wouldn't have learned to swim, I wouldn't have learned to ski, I wouldn't have gotten into video games and computer games.

"I would have become an old person simply because I wasn't surrounded by young people. And they are brilliant!"

He added: "We inspire each other. I climb trees and reinvent, relive memories I had." His willingness to be active and adventurous, in turn encourages his children to do the same, he said.

Kane added that being in late 60s means he has more time with his children in some ways because he's not devoting as much time to work, a decision he made after he and his wife experienced four miscarriages before his daughter Lyla was born. Now he works freelance "because I wanted to spend time with them".

As for the tiredness that comes with parenthood, Kane doesn't seem to be phased by it, sleeping typically five and a half hours a night, he said: "I don't seem to need much sleep."

"I get mentally tired sometimes, particularly when it's been a long working day as well, just writing and doing interviews. But luckily it's a blessed thing, I don't often get physically tired."
