Meghan Cox Gurdon (mother of 5) in the WSJ:

She comments on the resurgence of the large family on the big screen, but that the subtheme of these films is chaos, either barely controlled or actual. But in reality:

The odd thing is that, off the screen, large families are seldom the ones with wildly misbehaving children. In real life, they tend to be the orderly people with the polite children, the families in which older siblings can be seen caring for their little brothers and sisters without griping about it. Indeed, onlookers are so taken in by the popular stereotype that they are often surprised to see a large family acting peacefully.

The recent return of big families to the screen is both telling and pleasing. It will be more pleasing still when those families are able to appear not solely amid zany pandemonium but also in orderly accommodation with the rest of society. Then reel life will be a whole lot closer to real life.
