He and his wife, Priscilla Chan, wrote an open letter to their family's latest addition.
In it, the Facebook founder writes about his desires for his daughter to experience all sorts of things that couldn't possibly exist on the Facebook platform:
I hope you take time to smell all the flowers and put all the leaves you want in your bucket now. I hope you read your favorite Dr. Seuss books so many times you start inventing your own stories about the Vipper of Vipp. I hope you ride the carousel with Max until you've tamed every color horse. I hope you run as many laps around our living room and yard as you want. And then I hope you take a lot of naps. I hope you're a great sleeper. And I hope even in your dreams you can feel how much we love you.
