For parents like the Timmermons in Milwaukee, who diligently pre-screen G-rated movies and forbid their daughter from playing with the made-up and mini-skirted Bratz dolls, when and how to start talking about the human body and sex can be a bit of a mystery.
Schools face a similar dilemma. Many districts teach what's broadly known as human growth and development, but the thoroughness of the information varies widely among districts, schools and classrooms, based on an informal survey of schools by the Journal Sentinel.
Over the summer, Milwaukee Public Schools is addressing the unevenness in its human growth and development curriculum by revamping the entire program from kindergarten through high school, and making a plan to train teachers on how to deliver the information.
