This paper illustrates that a storybook for children has a specific characteristic to be used as a medium to gain information on children's growth and development. This claim was revealed from research conducted to describe a storybook for children which contains information to prevent malnutrition, which has remained high in recent years in Indonesia. The study involved 11 informants from various backgrounds relevant to the book's development. Their opinions become the data of this research. The data was gained from an in-depth interview and a focus group discussion. To get supportive information, the researchers used an audio recording technic during the discussion, complete with written responses over a questionnaire. The initial results indicated that a book for children aged three to five should have specific criteria from the cover, the character, and the setting. This research is an ongoing project. Thus, the following steps will be book authoring, review, and field testing.
