Speaking with PEOPLE in January, Adam and MacKinnon revealed they were expecting a boy and talked about looking forward to all the memories they'll make with their little one, The two explained that while their minds were flooded with ideas for their son and their family's future, they were also enjoying the moment.

"I think we are most excited just becoming parents at all! It is a dream we have both always had, and it is wild to think it’s only a matter of weeks away," Adam shared at the time.

"I hear so often that having a baby flips your world upside down. While to some that can be more of a scary thing, I think the both of us are really excited for that flip, and everything that comes with it."

The couple first revealed their exciting baby news in December, telling PEOPLE they could already picture life out on the road as a family.

"We talk about it all the time. The music industry is tough and unpredictable and anything but easy, but it's definitely our dream to be able to bring a separate bus out and tour the country with our little family," Adam said.

"I know if the fans had their way, MacKinnon would be at every single show. I think she has more fans than I do," he laughed. "But we love being able to do that together. Our communication, our lives are just easier and better when we are able to be together."

"We're praying and trying to manifest that time together with our family, and that this music coming out is going to lead us to that point where we get to have those experiences together."
