Indian children face a high risk of congenital hypothyroidism, leading to irreversible brain damage if undetected. Despite simple, inexpensive screening and treatment, policy neglect results in thousands of preventable disabilities annually. This article strongly advocates for universal newborn screening as a crucial early-childhood development intervention in India. It highlights cord-blood screening's administrative advantages over heel-prick testing for widespread implementation, emphasizing its feasibility and potential to transform child development outcomes. The authors urge national policy implementation, moving beyond scattered pilots to ensure comprehensive coverage and secure every child's future, promoting health and economic well-being.
