In this article I review the changes in thinking about childhood depression since the 1950s, with an emphasis on the struggles to find language for childhood depression. My interface with these changes is described, with a particular focus on the development of the Children's Depression Scale (CDS). Clinical applications of family therapy using the CDS in treatment of childhood depression are then illustrated with a composite case example. The idea is developed that depression in children can be seen as a blocked communication, and that increasing emotional expressiveness in families is an appropriate therapeutic aim and intervention. The relevance of the historical context to current practice is considered.
