Jesper Juul is a Danish family therapist and author of several books on parenting to a general audience. In his book Your Competent Child he argues that today's families are at an exciting crossroads because the destructive values — obedience, physical and emotional violence, and conformity — that governed traditional hierarchical families are being transformed. The book has so far been translated into 13 languages and has popularized current ideas of non-authoritarian parenting.
