Becoming a new parent has driven Priscilla Chan to work even harder to improve the world her daughter will grow up in, the wife of Facebook founder Mark Zuckerberg said in an exclusive interview with Savannah Guthrie, just one day after the couple announced a $3 billion investment to prevent, cure and manage all diseases.

"You just love that little being so much, more than you ever thought was possible. And you have so many hopes and dreams for that child," Chan told Savannah, explaining why she and her husband will ultimately give away 99 percent of their wealth. "And that drives me to want to work harder and invest now to make sure that the future is where it needs to be for all of our children."

Last November, Chan and her husband welcomed their daughter and first child, Max, whom she called "wonderful."

"Mark and I are just over-the-top proud of everything she does. She could be eating. She could be spitting. She could be sleeping. She could be just smiling and we're, like, ‘Oh, isn't that special?'" she said with a laugh.

Chan also opened up about why the couple decided to be so candid about their years-long struggle to conceive.

"There are really dark moments where you think you're alone. And when we realized that we weren't and that there were other people traveling along the same road with you,” she said. “I think having that, knowing that you're not alone, was incredibly important for us. And we wanted others to know that they weren't alone, either."

Photos of Max occasionally appear on the couple’s Facebook pages, which more reliably feature the family’s dog, Beast, who became a social media star thanks to his own page on the site.

Chan said don’t expect the same kind of exposure for her daughter.

"Max will have her own Facebook page, but she'll need to wait till she's 13 when she's old enough to have one," she said, referring to minimum age of users who want to create an account. "She has to follow the rules."
