Countries play a critical leadership role in the formation of the network. In 2018, eight countries are leading multi-stakeholder consultations to identify opportunities for coordinated ECD action at scale to advance progress towards the SDG targets for young children in their contexts. These countries will shape a global movement for young children as they explore how to meet young children’s developmental needs across several sectors and achieve the SDGs for young children. The lessons learned will provide the building blocks for ECDAN’s approach to engaging with other interested countries in subsequent years.
