Parents, dealing with the ups and downs of their adolescent child, may ask themselves: “What should I be expecting as normal with my child in adolescence?” In his latest book, The Space Between: A Parent’s Guide to Teenage Development, Walt Mueller approaches the topic with realistic and spiritually grounded optimism, the heart of an experienced parent, and the mind of someone who has dedicated himself to the topic over a 30 plus year career. He starts with some fundamental perspectives/truths and then moves through teenage changes physically, socially, intellectually, emotionally, and morally/spiritually. I especially appreciated his concise summaries of teens using Tim Keller’s categories related to identity formation – sexual partners, academic or athletic achievement, money and possessions, pleasure/gratification/comfort, relationships and approval, noble causes, and religion and morality. Packed with helpful quotes and up to date information on areas such as brain research, I found the book to be very accessible and at 120 pages a reasonable length for the intended parent audience. I bring it to your attention because I think it is a helpful tool for both parents and staff members at Christian middle and high schools.
