Childhood goes so quickly that we sometimes miss the greatest milestones of our children's lives – such as our baby's first steps.
So this dad decided to film each and every one of his little girl's so they'd never be forgotten.
Nick Turner, from New York, set up a camera and filmed his third daughter Lucy's daily attempts to try and walk.
She staggers, she stumbles, she falls on her bottom - and bounces right back up again. Until, finally, she takes her first steps.
And she has now become an internet star after Nick posted his time-lapse video online.
Story continues after video...
Nick told local news: "The process lasted months ... as you can see from the holiday decorations appearing and disappearing in the background. Maybe it was two and a half months total."
Since the video was uploaded to YouTube it has attracted more than 500,000 views.
Nick added: "Everyone seems to love the video, and I hope Lucy appreciates it someday."
