While pop-up books and moveable books of today are mostly created with children in mind, before 1700 AD books aimed specifically at children were simply not produced. Those few children who were lucky enough to be able to read had to content themselves with the material found in their parents' library.
In the early seventeenth century the development of the printing processes made the production of small, inexpensive books possible. The 'chapbook' thus came into being. Typically these were booklets of eight or twelve pages, often poorly illustrated and badly printed.
