It's been less than two weeks since Mark Zuckerberg became a father, and he's already a pro at diaper duty!
The Facebook CEO posted an adorable pic of him with little baby Max that showed him grinning from ear-to-ear with his firstborn.
"One more down, thousands to go," the 31-year-old posted. Looks like the new dad has the right attitude!
Zuckerberg's wife Priscilla Chan liked the family photo as did Sheryl Sandberg.
Earlier this month, the happy couple announced the arrival of their daughter and wrote an emotional letter on Facebook about their gift in her honor.
