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.
