The book "The Book of the Child: An Attempt to Recreate What is in the Mind of Children" by Frederick Douglass Howe opens the reader to the wonderful world of the inner world of children. The author tries to carefully and directly immerse himself in the thoughts, feelings and ideas of small people, trying to understand their ideas about the world around them, the development and perception of various phenomena. Howe shares his observations and conclusions about how children perceive information, how they interact with the environment, what their dreams and experiences are. This book opens new horizons of understanding the world of childhood and can become an indispensable source of information for parents, teachers and all those interested in psychology and child development.
