The Business of Being Born included footage and details of Lake's own "life-changing" home-birthing experience and followed a midwife going about her work. Tribeca called it "The Inconvenient Truth of Childbirth". Lake described it as her life's work for the last three years and expressed hopes that the film educated and empowered people to really know their choices in childbirth. She performed in the CBS television special Loving Leah in January of that year. Lake also jointly wrote a book on the world of natural childbirth and birthing options, along with Abby Epstein and Jacques Moritz, Your Best Birth, which was published by Wellness Central on May 1, 2009. Lake and Epstein also launched MyBestBirth.com, an online social network, powered by Ning, intended to allow parents and medical professionals to dialogue about varying birthing options and resources. Lake returned to television on May 11, 2009, succeeding Sharon Osbourne as host for the third season of VH1's Charm School. On November 10, 2010, Lake joined fellow talkers Phil Donahue, Sally Jessy Raphael, Geraldo Rivera, and Montel Williams as guests of Oprah Winfrey on The Oprah Winfrey Show, marking the first time those hosts ever appeared together on one show since their programs left the air.
