The book, titled "A Smart Girl's Guide: Body Image," which is marketed to girls ages 3 to 12, encourages children to talk with a doctor if they are questioning their gender identity.
"At first, you and the doctor might talk about wearing the clothes and using the pronouns (like he, she, or they) that make you feel most like the true you," the book reads. "If you haven't gone through puberty yet, the doctor might offer medicine to delay your body's changes, giving you more time to think about your gender identity."
