School of Infancy (Czech: Informatorium školy mateřské, full title:Soustavné pojednání o výchově předškolních dětí) is the first written work in the field of preschool education in world literature on pedagogy.
This work is unique in that it is the first early modern systematic treatise on the upbringing of children in the youngest age group.
The impact of the work was felt primarily in later times, not directly during the author's lifetime.
It is the first work of its time (17th century) in which the necessity of caring for the youngest children is justified.
Despite the fact that the field of child psychology did not exist at that time, Comenius's ideas have not lost their relevance.
