The second set of quadruplets to be born in Estonia this century entered the world yesterday on World Children's Day. The three boys and one girl were born at East-Tallinn Central Hospital (ITK) and each weigh between 1.4 to 1.8 kilograms. The children were born prematurely and are all healthy, they have two older siblings. In 2017 Estonia's first set of quadruplets — Loore, Luise, Leene and Lagle — were born at the same hospital. Last year, 3,293 babies were born at East-Tallinn's Central Hospital, including 58 pairs of twins.
