Mark Zuckerberg Announces Wife Is Pregnant, Opens Up About Past Miscarriage

Mark Zuckerberg is officially in the running for world's cutest dad.

A little over a week after the Facebook creator and his wife, Priscilla Chan, announced the birth of Max, the couple's first child together, Zuckerberg took to the social networking site to share a photo of himself happily changing his daughter's diaper. SPOILER: It's adorable!

Looks like he's already enjoying all the duties of fatherhood, as he and Priscilla read to their little bundle of joy just one day earlier.

"My next book for A Year of Books is Quantum Physics for Babies," the 31-year-old joked in a caption of another snap. "I am loving reading to Max," he added. "Next year looks like it's going to be A Year of Children's Books!"

My next book for A Year of Books is Quantum Physics for Babies!Just kidding. It's actually World Order by Henry...

PHOTOS: Stars Share Pic of Their Cute Kids

Just hours after the couple made the exciting announcement, Zuckerberg was photographed cuddling up close to his newborn. "Full of joy with little Max," he wrote.

Zuckerberg and Chan are "so happy" to welcome Max into the world, as their road to parenthood hasn't been easy. When the couple announced they were expecting in a lengthy Facebook post in July, they also revealed Chan had suffered three miscarriages along the way.

"It's a lonely experience," Zuckerberg wrote at the time. "Most people don't discuss miscarriages because you worry your problems will distance you or reflect upon you -- as if you're defective or did something to cause this. So you struggle on your own."

"We hope that sharing our experience will give more people the same hope we felt and will help more people feel comfortable sharing their stories as well," he added.
