Two days after Lenore Skenazy wrote the column “Why I Let My 9-Year-Old Ride the Subway Alone” she found herself on The Today Show, MSNBC, FoxNews and NPR, defending herself. She got the nickname “America’s Worst Mom.” (Nice.) She went on to write the Free-Range Kids, the book that became a movement. Now she is president and co-founder with Professors Jonathan Haidt and Peter Gray of the nonprofit Let Grow, which promotes childhood independence. She has lectured everywhere from Dreamworks to Microsoft to the Bulgarian Happiness Festival (for real!) Plus: She used to write for Mad Magazine! (Anyone remember Mad?) She lives in New York City with her husband and beloved computer. Her kids have flown the coop, which is good for “Proof of concept” purposes, but she misses them.
