This chapter introduces Coleman and Putnam’s social capital theory and discusses its potential for inspiring reflection on the social practice of ECEC’s collaboration with children’s families. Specifically, the theory promotes reflection on the relationships that develop through a new community of parents and professionals coming together, as well as the new interconnectedness among the parents, which extends the social capital of a particular family and becomes a profitable investment in the child’s future. Understanding the concept of social capital allows for the identification of which forms are being blocked, as well as the bridging and bonding that are not occurring. The empirical case presented in this chapter highlights the role of ECEC’s recognition of a family’s culture as a bridge to the parental community. The chapter concludes with a discussion of ECEC’s role in strengthening the family’s network in times where intense migration, mobility, and other factors may impede its growth.
