Долой наказания детей! Для новой жизни - новое воспитание
One of my personal favorites :)
Text translated from the poster
For a new life, a new upbringing.
Abusive treatment of a child drives him or her from the family to homelessness.
Create a joyful working life for the child, and there will be no need for punishment.
Influence the child is necessary:
By a good example, a caring, affectionate attitude, friendly advice, firmness in demands understood by the child, help in organizing the child's life - labor, creative, social.
If you do not know how to deal with the child - seek advice:
in the pedagogical counseling, in the school, in the kindergarten, in the pioneer group - they will help.
