The couple also announced the "Chan Zuckerberg Initiative to join people across the world to advance human potential and promote equality for all children in the next generation," adding that "We will give 99% of our Facebook shares -- currently about $45 billion -- during our lives to advance this mission."

"Max, we love you and feel a great responsibility to leave the world a better place for you and all children," Zuckerberg and Chan concluded. "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."
