This comes after Barker relished in his role as daddy all over again – he already has two kids with ex Shanna Moakler (20-year-old son Travis and 18-year-old daughter Alabam) and a stepdaughter named Atiana he is very close to.

‘The most wonderful thing you could do at any time in your life is have a baby or bring a human being into this world,’ Barker, 48, told People, before sharing how he first got a ‘crash course’ in parenting.

‘I love being a dad,’ the All The Small Things star confessed, before adding, ‘That’s my favorite accomplishment, it’s my favorite thing I get to do every day.’

Barker, who has now been married to Kardashian for more than two years, also recalled the time that he first found out he was having his son Landon, and how it inspired him to

‘The day I found out, I left my house and I ran to the freeway, he said of his impromptu run. ‘It was four miles, and then I ran four miles back, too.’

He deducted that he was so overjoyed at the prospect of being a dad that he ‘had this urge to just be the best version of myself, be healthy and take care of myself more — and I think that’s never gone away.’

In fact, that enthusiasm for being a dad again can be seen in some of the photos that he and his wife share on their respective Instagram pages.

The couple are parents to a blended family of seven that includes Alabama Barker, 25, Reign Disick, eight, Landon Barker, 20, and Atiana De La Hoya, 25, who are pictured in April 2022
