Zuckerdad is a daddy again and all I can say is "wow!" On his carefully managed Facebook page — a crafty mix of self-adulation, general PR, and business thoughts maintained by 12 employees — the Facebook CEO announced that his wife Dr. Priscilla Chan is expecting the couple's second child. Their first, a girl named Max, was born in 2015.

"Priscilla and I are happy to share we're expecting another baby girl!" Zuckerberg wrote this morning, while also alluding to several miscarriages Chan had experienced before having Max, about which she spoke publicly in an effort to address the stigma that too frequently surrounds them.

"After our difficult experience having Max, we weren't sure what to expect or whether we'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."

Indeed, Zuckerberg leads us to believe that he and Chan are having a girl on purpose to celebrate women. Extremely generous!

I grew up with three sisters and they taught me to learn from smart, strong women. 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.

Priscilla grew up with two sisters and they taught her the importance of family, caring for others and hard work. They supported each other as first generation college students and in their careers in medicine and business. They have so many inside jokes -- the kind only siblings can understand.

We are all better people because of the strong women in our lives -- sisters, mothers and friends. We can't wait to welcome our new little one and do our best to raise another strong woman.

Mark is 100 percent right. Women are so cool, in fact, that you can't even have a male child without one.

I do have one worry: When baby Max was born, Zuck wrote her a long letter about her bright future and announced he and Chan would donate 99 percent of their Facebook stock, the equivalent of $45 billion at the time, to charity. That eventually went to the Chan Zuckerberg Initiative, which is technically an LLC with a charitable focus. My question is, will Max's younger sister get equal treatment, or suffer the sad fate of most second children? I mean, what's Zuck gonna do for a grand gesture here — give away the remaining one percent of their stock?
