The peculiarities of the interaction between children and parents are highlighted from the position of the respondents, who have been grouped into subgroups according to the order of birth in the family hierarchy (N = 265). The choice of methods for studying the family interaction of the respondents has been found. The aim is to study the level of development of parent–child and sibling relations, and compare the results in the “The first/middle/last child” subgroups. The methods are questionnaires used to establish the level of parent–child and sibling relationships; the statistical processing of empirical data and graphical presentation of the results were done using MS Excel and IBM SPSS Statistics (v. 27.0).
