Happy Mother's Day Moms. If you don't have enough children to watch with your own brood, check out this fantastic and non-hokey documentary which was recently released.

It follows the first year of life for 4 babies, one born in Namibia, one in Mongolia, one in Tokyo, and one in San Francisco. It's fascinating to watch the similarities in these babies expressions and actions, despite the differences in their environments. Great, heart-warming documentary.
