The transformation of autonomous and often fragmented children's services into an integrated service is a topical issue in several countries [1-3]. The trend to offer more comprehensive youth services is stimulated by inclusive education policies, which aim to integrate children with special needs in mainstream childcare and school settings with the help of special staff. An integrated service with professionals from various disciplines who collaborate in the assessment and monitoring, providing support, health education, or referral [4] may be helpful in the early identification and treatment of children's behavioural problems and developmental delays. In some countries, multi-professional teams already operate in communitybased settings, like childcare and schools, but integrated community services for children and their families are certainly not self-evident [5, 6]. Transforming the workforce in regular communitybased care brings together different professionals (e.g., caregivers, teachers, social workers, nurses and youth care specialists) from various sectors, including early childhood education and care, primary schools, social work and youth care. This interprofessional collaboration in a 'team around the child' has only a relatively brief history, acknowledging differences between countries. IPC is certainly not self-evident for many individual practitioners, the interprofessional teams and their organisations which aim 'to meet special needs in ordinary schools', as Hanko (1986) [7] put it concisely. However, there is a growing interest in interprofessional teams in community-based services for youth [8, 9]. Reviews of IPC, which predominantly relate to health care, have revealed a number of important barriers and facilitators of IPC [10-16]. Some studies that explored the relatively new territory of children's services, have also suggested factors that foster or hinder effective IPC. At individual level, working experience [10] and interprofessional education with cross-service training may contribute to fruitful collaboration [17, 18]. At team level, regular meetings, mutual trust, clarity about one's own and others' professional roles [7, 19] and shared team goals [20] contribute to open communication and shared decision
