Zuckerberg then went on to explain that he and his wife are thrilled to be welcoming another daughter to their family, which he admits is made up on some seriously strong and empowered women.

“I grew up with three sisters and they taught me to learn from smart, strong women,” he writes. “They weren't just my sisters but some of my best friends. They've gone on to write books, excel at performance, music, sports, cooking and their careers. They showed me how to compete and still laugh together afterwards.”

He goes on to talk about his wife’s two sisters, whom he praises for having “supported each other as first generation college students and in their careers in medicine and business.

“They have so many inside jokes,” he adds, “the kind only siblings can understand.”

Zuckerberg admits that he “cannot think of a greater gift than having a sister,” before going on to praise all of “the strong women in our lives”.
