Boyd and Taylor tied the knot in April 2016, four months after welcoming Dakota. Back in July, The Voice season 7 winner shared a hilarious photo with PEOPLE to announce they were expecting.

“We will soon be #outnumbered #babyboyd,” a sign reads next to the family, while Jaxon holds onto a rope binding the parents-to-be. Meanwhile, Dakota is perched on her dad’s shoulders, and “IT’S A BOY!” can be seen written on a window in blue.
