Early intervention is a process of informing, consulting and providing support to families and their children until the age of six. For its success it is very important to detect problems in the child in time, and then start an early implementation of interdisciplinary intervention programs. In the process of early intervention it is necessary to establish a team work and cooperation among the experts. In this study, a special attention is given to parents’ experience about the work of “Kabinet za ranu intervenciju Caritasa Zadarske nadbiskupije” and of the "Leptirići" organisation in Metković. Moreover, what is determined with this paper are the parents’ opinions about the Cabinet and “Leptirići” organisation’s work, their satisfactions with the received services, the collaboration among the experts and whether there is a difference between Zadar and Metković parents’ attitudes. For this purpose, a qualitative research based on semi-structured interviews with 10 interviewees is conducted. Thus, an occasional sampling is used for collecting interviewees in Zadar and the snowball principle is used for collecting interviewees in Metković. The research results show that parents are generally satisfied with the received services. However, unavailability of information and a lack of individual work with the children is criticised. Also, they are mostly satisfied with the cooperation among experts and they emphasise that the received services are aimed at the whole family, and not just the child. There is no great difference between the opinions of parents from Zadar and Metković as they coincide in most of the categories. Parents involved in the "Leptirići" organisation compared the service possibilities in Metković with other cities, and some of them concluded that they would change nothing whilst others stress that they would have more opportunities for a better development of their children in larger cities.
