This guide offers important background information and practical steps for parents who want to have conversations about sex, relationships, and expectations with their kids: either in addition to health education class in school, or in place of it. While we do promote a developmental approach and starting these conversations with children as young as 3, parents of pre-teens and teens may find this guide most helpful and relevant. This guide offers 4 easy steps through the acronym OPEN, which stands for: Openly Communicate, Provide Information, Encourage Questions, and Normalize Puberty & Sex. A must-read for all parents.
