The science and practice of early childhood development now stands ready to address the needs and ensure the rights of infants and young children with disabilities and their families, among the most underserved and marginalized in all regions of the world. Synergies in global policies such as the "United Nations Convention on the Rights of the Child, United Nations Convention on the Rights of Persons With Disabilities" (CRPD), and Sustainable Development Goals resolute in "leaving no one behind" guide innovations in inclusive early childhood development (IECD). Concepts and tools such as the Early Childhood Quality Inclusion Profile (ECQUIP) and "triple-twin-tracking" facilitate holistic, comprehensive, and equitable policies and practices increasingly evident in international and global initiatives for nurturing care for all children.
