In my latest book, "Grandma Was Right After All!," I take the top 25 parenting sayings of my youth and explain what they really meant. I do so because they’ve been distorted and demonized by the mental health community as psychologically harmful, which is balderdash given that child mental health is ten times worse today than it was in the 1950s, when their usage was commonplace. The demonization prize goes to “Because I said so,” which when stated calmly and straightforwardly is nothing more harmful than an affirmation of the legitimacy of parental authority.
