Book excerpt: A new kind of puberty guide, You-ology embraces an inclusive gender-affirming approach that normalizes puberty for all kids. Kids may not know where to go to get accurate information about how they and their peers are changing. Traditional puberty education--splitting up kids according to assumed gender identity--only contributes to a sense of isolation and often does not include all kids' experience of puberty, fostering shame and secrecy in cisgender kids, alienating kids who may be gender diverse, and leaving kids with questions about how puberty will affect their friends and classmates. In addition to discussing puberty in cisgender kids, You-ology speaks to kids who are gender diverse and intersex, who will see themselves reflected in these gender-affirming pages. Colorful illustrations keep the tone upbeat and engaging, while short stories featuring a cast of diverse characters add relatability and humor. For curious kids and parents looking to talk about puberty in an inclusive way, You-ology offers fact-based, age-appropriate, and body positive information about the physical, social, and emotional changes ahead for all kids.
