"When I was a baby and took my first steps, my mom wrote the date in a baby book. When my sister's children took their first steps, she recorded it with photos and videos," Zuckerberg wrote.
But Zuckerberg wanted more than just posting a lame picture or status update announcing that this daughter, Max, could now walk.
So instead of a traditional photo or video, Zuckerberg posted this 360-degree video on Friday that shows Max walking towards him, a feature the social network launched in September.
