Yahoo! Movies just dropped this ridiculously cute trailer for Babies, a documentary that follows four babies from around the world -- from birth to first steps. Kind of like Disneynature's Earth, except with, you know, babies. Guaranteed to stir your biological clock.

Among the four kids are Bayarjargal, who resides with his family in Mongolia, near Bayanchandmani; and Mari, who lives with her family in Tokyo, Japan. I imagine the film is a lot of cut shots of kids falling down and stuff. The movie is scheduled to hit theaters in April from Focus Features.
