The aim of the study is to assess mental and somatic symptoms of preterm born children at the ages of 2, 5 and 10 by a multidisciplinary team and to evaluate an app that screens for these symptoms. Furthermore, there will be an evaluation of an intervention by our multidisciplinary team that provides recommendations for further treatment and diagnostic procedures of the children.

• T0: App-questions for the children at the ages of 5 and 10 and the parents of all children to mental, somatic and sleep problems of the children and well-being of the parents, sleep tracking and recording of a sleep sequence of the children; differentiated examinations and questionnaires to mental and somatic problems of the children by interdisciplinary study team
• Interdisciplinary study team meeting to generate recommendations for the families
