Infant 2 School (I2S) is a new, individualised family-centred early intervention, and health and development promotion programme that is designed to be delivered by community nursery nurses (CNN) from within health visiting teams. The programme aims to address identified service gaps by supporting and complimenting the work that health visitors do so that vulnerable families needing additional help have access to evidence-based interventions in a timely manner. I2S was recently launched in the UK and this paper provides an overview of the programme including its origin, structure, content, benefits and anticipated outcomes for children and families.
