The “Need a Bar Sometimes” singer said that Mary-Elizabeth was hoping for a sister but quickly came around to having another brother in the mix.
“The shock of it being another boy, for Mary, it lasted a couple of hours. There were some tears shed, I won’t lie,” Walker said with a laugh. “It was because of expectation, but that was overcome with the thought that we’re not in control of that. We don’t decide if it’s a boy or girl, and she was able to understand that after a while.”
Walker also told PEOPLE about the significance of naming his son Christiaan, a nod to Walker’s great-great-grandfather Christian, who immigrated to the U.S. from Denmark in 1808 and eventually settled in the singer’s hometown of Beaumont, Texas.
“Everyone called him ‘The Dane,’ and Jess and I are really excited to be able to name [our son] after that man,” he said in August. “I always heard the stories about what a great cow man he was, and so as I was growing up, my dad was a cow man and passed that down to me and here I am passing it down to my three sons — soon to be four sons, named after the guy that started it all. So it’s a pretty nice circle of life.”
Walker also gave a shout out to his loving wife, calling Jessica “a saint.”
“I can honestly say that she’s a saint, and everyone around her knows it too,” he said. “She absolutely loves being a mom. It’s the toughest job on Earth, and I wish there was more adoration and homage paid to mothers because there’s not a more unselfish way of life than being a mom. It’s tough. And it’s worth it.”
