He's ready for daddy duty!

Rob Kardashian is gearing up for the birth of his first child with Blac Chyna, and he shared his excitement by posting a new sonogram photo of his baby girl. "Can't wait for you," he captioned the image. Aww!

The only boy of the K clan has battled weight gain, diabetes, and depression in recent years, but his fiancee's maternal instincts are what motivated him to become a changed man and start his own family.

"I'm just so attracted to how she raises her son, King. That's what attracted me to her initially. She was just a great mom ... and [that] led me to want to start a family with Chyna. It's something I've always wanted to do," he explained during a Facebook live chat earlier this month.

We're happy he's happy, we just hope he realizes what a massive responsibility parenthood is!
