In a still from "Babies," a Nigerian mom kisses her absurdly adorable kidlet.

If you’re in your 20s or 30s and haven’t had a child yet, then there’s a new documentary I must warn you about. It’s called simply “Babies: The Documentary,” and it may convince you to run right out and conceive (or adopt).

The film follows four babies from four regions of the world — Nigeria, Tokyo, San Francisco, and Mongolia — through their first year of life. Oh, it ostensibly has deep things to say about socioeconomic conditions and childrearing practices worldwide, but all that is just a convenient cover for what the movie’s really about: giving you a chance to squee over adorable babies for two hours. The National Geographic-style shots of the Himalayas cross-cut with scenes of Tokyo traffic and yuppieish Americans in a Jacuzzi are simply throwaways, impossible to take seriously when juxtaposed with the all-powerful CUTE. There’s a baby playing with a cat, for heaven’s sakes! A baby industriously squishing a potato against a rock! A baby inadvertently sharing its bath water with a thirsty sheep!

What with the international kidlets and all, this documentary can turn you into Angelina Jolie. In fact, I’m half convinced my parents and in-laws made it as part of an insidious plot to get themselves a grandkid.
