Usually children don’t really like to go to bed; it’s not easy to persuade them to leave their toys and calm down after an active day. In such cases, a book always came to the rescue. Reading to a child before bed is a good way to switch his attention from activity to relaxation. For this purpose, the lullaby fairy tale “Like a wolf cub searched for the day” is perfect. While being kind, with bright and colorful illustrations, this book is also educational, telling in a very accessible way about the Earth and the Sun, as well as why all people need sleep and rest. Such thematic content and at the same time calm, kind presentation have a calming effect on a child of preschool and primary school age, preparing him for sleep.
