Book excerpt: Author Jim Burns believes the key to instiling in children a healthy, values-centered view of sexuality is to start the discussion early--being open and honest at every stage. The Pure Foundations series is already guiding parents of preteens and teens through potentially awkward conversations. Now two fully illustrated books--one for pre-readers and one for early readers--complete the series. How God Makes Babies is an age-appropriate introduction to basic sexuality, helping children ages 6 to 9 understand that God created males and females differently and with a purpose, emphasizing that God is a part of each family from conception to death.
