The study has described the path from the child’s birth to date, along so with the expectations for the future. In this case, the child has a slow psychomotor development. The first part of the paper represents the theoretical background of children with special needs, children with developmental difficulties and the families of such children. The second part of the paper presents brief theoretical descriptions of case study method and semi-structured interviews which were used in this study. The research was conducted on a family of five, where the youngest child has a slow psychomotor development. The research was carried out by three semi-structured interviews with parent and the oldest child. After analysing the results, an insight into the everyday life of a family with a disabled child was described. This covered a variety of areas, such as: the problems family encountered on their path, the support they had, the personal growth they experienced as well as the influence of their family and friends.
