Former Disney Star Debby Ryan and Husband Josh Dun Welcome Their First Baby

Debby Ryan and Josh Dun are officially a family of three!

On Saturday, Dec. 13, the actress, 32, shared on Instagram that she and the Twenty One Pilots drummer, 37, welcomed their first child — a baby girl named Felix Winter Dun — during a home birth.

“We sat under the full moon — the cold supermoon — reminiscing on our life as a family of two, and told the child I was harboring that we were ready to become three,” Ryan wrote on Instagram. “By midday, Felix was born under Christmas lights with snow outside our bedroom window, right into her father’s hands.”

Alongside the announcement, the Disney Channel alum shared a video of Dun comforting her while she sat in a birthing tub with calming music playing in the background. She commended him in the caption of her post for being an “incredible teammate” during the birth of their first child. 

“Somehow didn’t get pulled into the tub and drowned and is taking such good care of his girls on this side of things,” Ryan said of Dun. “I was fortified by an incredible birth team, and the strength and wisdom of some women who have supported me on this journey near and far.”

In the post, the Insatiable actress also shared a photo of her daughter sleeping with her hands resting under her chin and another showing Dun lying with their daughter on his stomach and their dog nearby.

“Her hair is made of silk and her breath smells like vanilla ice cream and every chirp, squeak and whimper is music and everytime I look away and look back, she’s gotten smaller somehow,” Ryan gushed in the caption. “I know too soon, I’ll look away and look back and she’ll be bigger and bigger still so for now I’d like to spend my days trapped under the immovable 8 pounds of Felix Winter Dun.”

“I’ve been a lot of things but her home, a grow light, a portal to bring a new soul into the world — these are my greatest honors,” she concluded. “Welcome to earth lil moonbeam. Love you forever. 🌙✨”

The couple, who began dating back in 2013 before secretly tying the knot in December 2019, announced that they would be welcoming a new addition to their family on Sept. 8 with a joint post on Instagram. 

Alongside images of herself showing off her baby bump and a few ultrasound photos, Ryan captioned the post, “Dun&dun +one.”
