The family is the most important and most valuable community, the reason for our existence, where one can always count on the members of his family, feel protected and loved by them, when they need to talk about his problems, but they are also in good times. With one's family members, an individual builds mutual respect but also assumes responsibility for his (non) deeds. Since parenting is the most important role of every adult, it should possess the child's ability to focus on the proper growth and development and positive development of the person with regard to the developmental age of the child.

This paper presents a study involving 252 parents of pre-school and early school children. A questionnaire consisting of three parts was used. The first part consisted of general questions of the closed type (age, gender, level of education, age of the child, order of birth of the child). The second part consisted of a knowledge base on child development and parental practice that consisted of 11 questions. The results show that parents of pre-school and early school-age children differ in parenting attitudes considering the fact that parents have a decisive influence on the child and that parental involvement is crucial for the healthy and complete development of the child. Parents of pre-school age children consider the role of parents in child development judgments more widely
