The article is an attempt to unravel the mystery of education in a family based on the continuing validity of Janusz Korczak’s thoughts in his brilliant and timeless essay How to Love a Child. In the book, divided into 116 autonomous parts, the Old Doctor is trying „to learn, to understand and to love the child”, to touch the essence of parenthood. He studies the situation of a child in a family basing on three aspects: with reference to the child, to his parents and to the mutual relations between them. As a result, there came into existence three distinct fields of investigation. The first one constitutes the child, the second one- an adult, in this case a parent, and the last field of investigation constitutes connections between children and parents.
