Ever since welcoming his bundle of joy earlier this month, the proud new father hasn't been able to stop sharing photos on social media. Stagliano posted the first when little Bowen was just two days old, along with a sweet message about his wife and son.

"There certainly aren't words enough to describe how much this picture means to @emilystag and I. But here's my attempt," Stagliano shared on Instagram, along with the hashtag, "#Stagclan." "Bowen Michael Stagliano came a month early (he really wanted to hang out with us). He was born at 6:33am, and came into the world just as the sun was rising over the mountains through the window outside the delivery room. He and Mom are doing great! Because he got here early he's spending a few extra days in the NICU... and I can't...stop...smiling. He's doing well. We will bring him home on Saturday. Thanks for all the love and support for our little guy."

While getting strong in NICU, baby Bowen spent some quality time with his dad...

...and met his grandparents.

The proud parents were finally able to bring their little one home on Oct. 17.

Stagliano is famous for his runs on both Bachelor Pad and season five of The Bachelorette, but he's come a long way since being at the Bachelor mansion.

Earlier in the week, he posted a video of Bowen with his 2-year-old cousin, Addison, captioned, "Lots of tears while this was going on. I did 15 push-ups afterwards to compensate."

Addison is the daughter of Stagliano’s twin brother Stephen, who is now married to former Bachelorette DeAnna Pappas Stagliano. The couple also has a 9-month-old son, Austin.

And in the wee hours of Friday morning, Stagliano snuck a sweet selfie of his late-night baby duties.

It's official -- Stagliano's heart is officially "melted."

Congratulations to the happy family!
