This article focusses on the faith formation and ability of preschool children to defend their faith from as early as the early childhood phase (two to six years). The research investigates prominent psychological theories that cover preschool children’s cognitive development to determine if children within this age group can constructively partake in faith formation, as well as the role that parents have in encouraging and shaping this faith formation and apologetic ability. The article provides apologetic guidelines from the Reformed tradition to parents to assist them in this task.
