Personality is what each person is unique for, the way they behave, that is, the characteristics of a person that they were born with or adopted during their life. A child is born with a temperament, and personality traits are partly inherited, while on the other hand there is clear evidence that they are created with the help of upbringing and the influence of the environment. There are many factors of personality development, and one of the most important is the family in which the child grows up and develops. The family is the first and most important social community that provides the foundation of a child's personality and raises him using their family values. There are almost no studies on the connection between family upbringing and the development of personality in children, but it can certainly be said that the parental style of raising a child and the personality of the parents have a significant influence on the development of the child's personality. The aim of the paper is to investigate the opinion of parents about the development of their children’s personality, that is, to determine whether they understand how they can influence the development of a child’s personality. For the study, a focus group was conducted in which the children's mothers were questioned about the personalities of their own children, and about the possible influence of the family on the children's personalities. The answer they gave for the given questions provide insight into the existence of a link between the family and the child's personality.
