What’s the Big Secret? Talking about Sex with Girls and Boys by Laurene Krasny Brown and Marc Brown

Simple, straightforward, and age-appropriate answers to kids’ most common questions about sex, the human body, reproduction, and development.

Are boys and girls different on the inside? How do you tell girls and boys apart? Do girls and boys have the same feelings? Is sex a dirty word? Where do babies come from? What does being pregnant mean? How do you get a belly button? Tell me about when I was a baby…

With characteristic sensitivity and humor, the talented team who created Dinosaurs Divorce and When Dinosaurs Die presents helpful basic information, including answers to tough questions for preschoolers, early elementary students, and their teachers and caregivers.
