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.
"Priscilla and I are so happy to welcome our daughter Max into this world! For her birth, we wrote a letter to her about the world we hope she grows up in," the began by writing.
They shared that they "will give 99% of our Facebook shares—currently about $45 billion—during our lives to join many others in improving this world for the next generation…Like all parents, we want you to grow up in a world better than ours today."
Mark and Priscilla ended their detailed letter with a sweet sendoff:
"Max, we love you and feel a great responsibility to leave the world a better place for you and all children. We wish you a life filled with the same love, hope and joy you give us. We can't wait to see what you bring to this world. Love, Mom and Dad."
