"The book was written by , a BA in Education, and Ph.D. in Social work, based on ideas she got after listening to a testimony video from an American psychiatrist (Dr. Stephen Levine, the specific video was recently removed from the internet) who has fifty years of experience in treating gender dysphoria. What the specialist said is that children naturally have a very simple and childlike perception of what it means to be a boy or a girl, and based on this, they categorize themselves into a "box" (certain toys, clothes, colors, hobbies, etc.). According to the specialist, his professional experience and research show, that the majority of children with gender dysphoria naturally desist from it within a few years, after reaching adolescence, as their perspective changes with time. The younger ones and their brains go through a maturation process, and the result is that, for the vast majority, instead of a simple and childlike perception of what it means to be a boy or a girl, they develop a more complex perception that allows gender non-conforming boys to be in the 'boys' box and the same for girls, so there is no need to change their bodies to fit into a 'box.'
