In this very special final episode of the season, the sisters are joined by the author of one of their very favorite shared books, Kim John Payne.

Years ago, Cait + Kara bonded over one of his many books, Simplicity Parenting, and so they are thrilled to welcome him to the show this week.

Kim, Cait and Kara discuss why parents don't need to to be on a constant quest to give their kids more, the gift of boredom and how we can simplify our kids' lives so they can become more who they truly are.

This is a new favorite, sisters!
