Another source previously shared with PEOPLE that Kardashian Barker was "over the moon about her son’s arrival," after her "pregnancy took a stressful turn towards the end."

"She is happy to just be able to snuggle her baby boy now," the source said at the time. "She feels so blessed."

The source also shared that Barker "keeps being amazing" to his wife and even supplied her with some "healthy food" at the hospital after she gave birth. "He makes sure she has everything that she needs,” the source added. “He is obsessed with their baby boy."

When Barker's oldest, Landon, was asked about his baby brother in November, the 20-year-old admitted he wasn't planning on being very hands-on with the infant.

In an interview with SiriusXM TikTok Radio, Landon was asked by host Jess Lucero if he had changed any diapers. He frankly said, “I have not and I will not be."

He was then questioned if he's adjusted to how he should hold the baby, to which he admitted, “I actually haven’t even held it!"
