Editorial: Regulatory problems and disorders in early childhood: aetiology, contextual factors, developmental outcomes and pathways, and treatment options

We are delighted to present a diverse selection of current research on early regulatory problems (RPs; i.e., excessive crying, sleeping, or feeding problems) and parent-child interactions. The articles in this special topic range from primary data studies of heterogeneous and diverse populations from Denmark, the USA, and Germany (both longitudinal, cross-sectional, and interventions), to meta-analytic approaches, and an expert opinion. After the last few decades empirically established a clear association of early RPs with risks for later childhood mental health (1, 2), we can now focus on the clinical and societal importance of this topic and underlying mechanisms.
