II National Congress of Paediatrics: The fight against child mortality.

In the present work, we present an overview of the contents of the communications presented at the Second National Congress of Paediatrics, held in San Sebastian in 1923, on the occasion of the 100th year anniversary. The problem of infant mortality stands out as a common thread, which in those years was very high in Spain and was a concern of politicians, intellectuals and the medical profession. It is worth noting that some of the proposals and concerns of the paediatricians who attended that congress continue to be relevant today.
