As part of my book-in-progress on libertarianism and the family, I've read several books on parenting and the contemporary family. My favorite may well be Lenore Skenazy's book Free Range Kids.  I sent her something of a fan letter that included a comment that her chapter titled"Don't Think Like a Lawyer" should have added"Do Think Like an Economist."  I explained why and she asked if I'd write it up as a guest blog.  That little essay has now appeared at her blog FreeRangeKids.com.
