Julie King and Joanna Faber are the co-author of books aimed at helping parents communicate well with their children, from pre schoolers to teens. Their previous survival guide to life with children aged 2 to 7 has been translated into 22 languages, they also have a companion app HOW TO TALK: Parenting Tips in Your Pocket, and the app Parenting Hero. Their new collaboration is the book How To Talk When Kids Won't Listen: Whining, Fighting, Meltdowns, Defiance, & other Challenges of Childhood. There's a delightful quote at the beginning of their book - which will resonate with parents and caregivers "Before I became a parent, I didn't know I could ruin someone's day by asking them to put pants on."
