Mark Zuckerberg and Priscilla Chan Are Going to Have Another Daughter

Mark Zuckerberg and wife Priscilla Chan announced they are expecting another daughter this year. 

This will be the couple's second child, joining Max, their first daughter, born in late 2015. 

The Facebook boss explained in a Facebook post that the news about their new child came a bit as a surprise, especially since they had troubles having Max, troubles that Zuckerberg has spoken about in the past. He says they weren't even sure they'd be able to have another child. 

"When Priscilla and I first found out she was pregnant again, our first hope was that the child would be healthy. My next hope was that it would be a girl. I cannot think of a greater gift than having a sister and I'm so happy Max and our new child will have each other," he said.
