It's only been a few weeks, but Jeff Lewis appears to be settling into fatherhood just fine. And to prove it, he posted an adorable snapshot of himself holding his baby girl, Monroe Christine Lewis, to Instragram over the weekend with a message reassuring fans he's got daddy duty on lock.

"Day 12 and she's still alive! #milestone #wegotthis #butwearetired," the Flipping Out designer shared, offering up another sneak peek at Monroe, who was born on October 25 via surrogate.

Actually, since the day Jeff welcomed Monroe into his life, he's shown off his softer side. "At 4:22pm today, I grew up. Welcome Monroe Christine Lewis," he revealed shortly after he birth alongside a photo of himself kissing his baby girl.

Monroe is the first child for Jeff and his longtime partner, Gage Edward. Below, Andy Cohen reacts to the couple's happy baby news.
