"Growing Steady and Strong: Early Childhood Development Regional Guidance in East Asia and the Pacific" was developed against the backdrop of the coronavirus disease (COVID-19) crisis to support the country offices of the United Nations Children's Fund (UNICEF) in implementing the early childhood development (ECD) agenda as a key pillar for UNICEF in 2022-2025. It aims to provide a vision for action to UNICEF country offices in East Asia and the Pacific and other interested ECD partners and stakeholders to enhance the ECD policies and programmes in the region and position its importance in policymakers' plans for a brighter future. Chapter 1 describes the purpose and rationale of the document. Chapter 2 highlights East Asia and the Pacific system-wide advances as well as challenges in ECD systems strengthening and integrated national policies. Chapter 3 summarizes the direct impacts on young children and their families in the region amidst the COVID-19 pandemic that has affected more than 150 million young children under 5 years of age. Finally, Chapter 4 details pathways to achieve the strategic vision of "Building back better for young children through ECD." The analysis suggests two key response pillars: systems strengthening and family and child-friendly policies. It also recommends five key policy actions.
