Book excerpt: An engaging introduction for very young children to the basic facts of life in a way that is gentle, age-appropriate and accessible. Research shows that children are learning about sex at an increasingly young age and often from undesirable sources. The Q&A format, with questions posed in the child's voice and answers starting simply and becoming gradually more in-depth, allows the adult to guide the conversation to a natural and satisfying conclusion. Additional questions at the back of the book allow for further discussion. Child psychologist Dr. Jillian Roberts designed the Just Enough series to empower parents/caregivers to start conversations with young ones about difficult or challenging subject matter. Other books in the series deal with diversity, death, separation and divorce.
