Mark Zuckerberg shared a sweet photo showing the new dad cuddling with his daughter, Max.

The 31-year-old billionaire posted the photo on his Facebook page, proving that he's just like proud new parents everywhere who can't help but share baby photos on the social network.

"Full of joy with little Max," he wrote. Zuckerberg and his wife, Dr. Priscilla Chan, welcomed Max during the week of Thanksgiving. Zuckerberg is currently taking two months paternity leave to spend time bonding with his new baby -- and it's clear by his smile in the photo that the new father is enjoying every minute of it.

Full of joy with little Max.

In an open letter to their daughter last week, Zuckerberg and Chan pledged to give 99 percent of their Facebook shares to the newly formed Chan Zuckerberg Initiative, a philanthropic group dedicated to tackling lofty goals, including curing disease, connecting the world and reducing poverty.
