It's Perfectly Normal: Changing Bodies, Growing Up, Sex, and Sexual Health is a children's book written by Robie Harris and illustrated by Michael Emberley.

Harris was prompted to write It's Perfectly Normal by her editor so young individuals would understand aspects of sexual health.

[3] The book has won multiple accolades and appraisal for its accurate information and its normalization of body changes and human sexuality.

[3] Later, she started to work at Bank Street Writer's Laboratory with two other children's book authors, Irma Black and Bill Hooks.

[9] Harris agreed to the idea, but believed that children needed to learn more about healthy sexuality than just HIV/AIDS, leading to the development of It's Perfectly Normal.

[2] According to Dell'Antonia of The New York Times, Harris, with the purpose of teaching young individuals accurate and resourceful information about sex, had consistently included details of sexual intercourse and the events leading to pregnancy as well as the aftermaths of birth in each edition.

[12] Additionally, Harris explains that everybody talks about sex and body parts with different reactions; some people are uncomfortable and some individuals make jokes about it.

[11] Harris and Emberley worked closely together on books specifically on sexual health because of the sensitivity of the topic, to ensure that each drawing would be clear and well-made.

[5] Robie Harris and Micheal Emberley constantly visit parents, teachers, librarians, doctors, nurses, psychologists, psychoanalysts, scientists and clergy for every new edition of the book published.

[2] Specifically, Harris makes sure that new details of AIDS prevention, birth control laws, gender, and sexual abuse are presented accurately in the book.

[5] Because of its up-to-date accuracy, It's Perfectly Normal is even used at Harvard Medical School to teach students particular sex cells like the sperm and egg.

[14] Other reviews said that the book is a useful resource that shares accurate information with a positive message about body changes and human sexuality.

Many sources believe that the book portrays sexual content that is not age appropriate, including illustrations of nudity and sex, homosexuality, abortion, and religious viewpoints.

He noted especially one page that showed three couples having sex, mostly unclothed, and another depicting a girl bent over, from behind, using a mirror to view her own exposed genitals from below.
