Aim: The aim of this study was to show similarities and differences between foster and biological parents in experiencing parenting difficulties. One of the hypotheses states that there are differences between biological and foster parents when it comes to a range of received and given support expected from both family and others. Methods: In this research an in-depth interview and a questionnaire designed by the author were used. The tool includes closed questions about parenting knowledge, skills, and competence in the upbringing and care of their children. Questions also focused on the resources of parents and outside support. Quality and quantity analysis was applied to a sense of support received and expected by parents. Results: The results obtained suggest a difference between biological and foster parents when it comes to the sense of support coming from outside. Specialists, institutions, other parents and teachers are more supportive towards foster parents than biological ones. Partners, family, friends (people close to family) are more supportive towards biological parents. Conclusions: There are differences both in terms of received and expected social and institutional support among biological and foster parents.
