The Tiniest Babies
The Tiniest Babies is the registry maintained by the University of Iowa. It contains the list of the worlds smallest surviving babies. This record is noteworthy since it is rare for babies weighing less than 400 grams to survive. The registry aims to collect data on the long-term health, growth and development of the recorded infants.
The worlds tiniest surviving babies were born before the average gestation period of 40 weeks. The worlds smallest surviving infant, who was discharged recently after a year in Neonatal Intensive Care Unit in Singapore, was born under 25 weeks. She weighed just around 212 grams and was just 24 cm long.
