Facebook giants Mark Zuckerberg and wife Priscilla Chan have announced that they are expecting a second daughter, joining their one-year-old daughter Max.

“After our difficult experience having Max, we weren’t sure what to expect or whether we’d be able to have another child, he wrote

“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 added

“We can’t wait to welcome our new little one and do our best to raise another strong woman.” He concluded
