Happy birthday, Max!
Facebook CEO Mark Zuckerberg and wife Priscilla Chan celebrated their baby girl's big day with party hats and one sweet family photo Wednesday.
"I can't believe it's been a year," the proud pop wrote.
That first year flies by for all parents, but it wasn't the only milestone Zuckerberg cherished this week.
He explained that Max "kissed me on the cheek for the first time yesterday."
Just a few weeks ago, he revealed Max's first word, too — but it wasn't dada.
Of course, more firsts lie ahead, and the family is looking forward to all of them.
"Here's to many more years of happiness and health for Max and all children around the world," he wrote.
And here's to many more baby photos — we hope!
