In the study, it has been investigated which difficulties can be found in the work aimed at children in families with addiction problems. The problem has been studied in two contexts, the work of school counselors in the school and the work of family processors with child groups. The focus of the study is on alcohol abuse. There are four qualitative interviews that have been completed. How the school's counselors discover children from families with substance abuse has been investigated. Children's signals, behaviour and roles have been addressed. The counselors difficulties in working with support for the child have been studied, here it emerged that space and resources are a contributing factor to the difficulties in the work. What difficulties the family therapists perceive in their work with the child groups are addressed. It appears that children's behaviour can prevent the child from participating in a group and that the family therapists consider that their professional role is not valued by others. The study examines how addiction problems in the family affect the child. During the course of the study, concepts such as guilt, shame, responsibility and parentification are addressed.
