While much has been done to address the situation of children around the world, much more needs to be done to ensure that the rights of all children are protected and that they are able to live up to their full potential. More needs to be done specifically to address the low funding and resource allocation to Early Childhood Development (ECD), slow implementation of polices, limited access to services particularly by the poor and vulnerable, variability in the quality of services as well as the lack of coordination amongst service providers in different sectors. As more country early childhood development networks emerge, it is important to look at the role advocacy networks play in ensuring that children are supported through holistic efforts that meet their health, nutrition, educational and cognitive developmental needs. This paper takes a case study approach looking at the impact of Advocacy Networks and the role played by the Zimbabwe Network of Early Childhood Development Actors in addressing early childhood development policy gaps and membership challenges in Zimbabwe.
