With current migratory movements, the population is becoming increasingly mixed, and consultations are receiving more migrants. The paediatrician or general practitioner is often the front-line health professional who has to assess how to welcome a newcomer family, investigate their life history, discuss mental health with them and sometimes overcome the negative prejudices that some cultures and people may have about psychiatry. Identifying worrying symptoms is an important first step in the overall assessment. It is then essential to support these families while working on protective factors and offering support for parenthood. Finally, working with the network will be key to ensuring continuity of care and the most appropriate support for the migrant's needs.
