Rating: PG for cultural and maternal nudity throughout.

What it's about: We follow babies from four different cultures through their first year of life.

The kid attractor factor: Seeing how babies entertain themselves in places without "Little Einsteins" DVDs.

Good lessons/bad lessons: Actually, it really does "take a village" to raise a child. Gadgets help.

Violence: None.

Language: Nearly dialogue free.

Sex: Infant and mother nudity.

Drugs: None.

Parents' advisory: A little childhood development and a lesson in the diversity of cultures, all in one kid-friendly documentary.

'Iron Man 2'

Rating: PG-13 for sequences of intense sci-fi action and violence, and some language.

What it's about: Iron Man has new foes to fight and new friends to help him fight them.

The kid attractor factor: A comic book adaptation with action and a little edge.

Good lessons/bad lessons: Sometimes, it isn't obvious just what parents pass down to their kids.

Violence: Lots and lots of it, with blood.

Language: Some profanity.

Sex: Scarlett Johansson joins the cast, and is leered over.

Drugs: Alcohol is consumed.

Parents' advisory: The fantasy-violence and profanity aren't so extreme as to make this unsuitable for anybody over age 10.
