The family is the first place and educational environment especially for children to develop their personality. Parents teach their children things such as self-control, values and social roles, so that when childern are mature enough to enter the secondary environment outside the family, the foundation of the personality has been well- formed. Socialization process would work well if the father and mother as parents can function well too. Father and mother create a partnership pattern in which the father has  equal rights to manage the household, especially educating children. Father (husband) can also perform public and domestic roles. This means that even though the father plays his role responsibly as an income getter, he could also serve the domestic affairs as the mother did.  This paper is the result of the research on the Role of Fathers in Early Childhood  Development in Labuhan Ratu Kedaton Bandar Lampung.The type of research is descriptive qualitative in which the researcher used this method in order to create an accurate and systematic description based on the facts about the role of fathers in the development of their children particularly children under five. The result of the research shows that the fathers mainly play two roles in the family, i.e. public and domestic roles. Public roles refer to the income getter of the family, whereas domestic roles cover stimulation, parenting, and education of the children. Keywords : Family, Roles of Fathers, Toddlers.
