"It’s Perfectly Normal" can be classified as a health manual for upper-elementary and middle- school audiences. According to the "Booklist", Harris and Emberley associated a clear and accurate illustration with every description. However, they were also considered to be humorous so it could be suitable for children. For example, the panels that showed female fertilization eggs transporting through the Fallopian tubes into the uterus; Harris showed the eggs screaming in joy as they traveled. Harris and Emberley worked closely together on books specifically on sexual health because of the sensitivity of the topic and that each drawing had to be clear and well-made. As stated by the "Horn Book Magazine", the illustrations are also considered to be done in a friendly style. Whether the person drawn is kissing or is participating in sexual intercourse, they are shown happily.

Harris also mentioned that she talks with these specialists of what should be healthy and age appropriate for these children to stay informed and make healthy choices; she does this with the text and illustrations. Harris stated that she does this for the safety of adolescent children that want to learn more about their changing bodies and feelings. Although the internet is available for searching these topics, she says that there are many creepy and dangerous websites that are unfortunately accessible.

Not only was the graphic novel praised for its reliability, but it was also commended for bringing awareness to children of puberty. According to "Kirkus Reviews", it is a source of education that is slowing the spread of sexual diseases and ignorance. Other reviews said that the book is a useful resource that shares accurate information with a positive message about body changes and human sexuality.
