A brother and sister born 126 days before their mother’s due date in Canada were named “the world’s most premature twins” by the Guinness Book of World Records on Saturday, their first birthday.
This is an atypical record, to say the least.
The duration of a pregnancy is usually nine months, or about 40 weeks.
Adiah and Adrial Nadarajah were born after only 22 weeks of development in Toronto, Canada, at a stage of development that rarely ensures the survival of newborns, reports the BBC.
Weighing between them less than 750 grams at birth, they are also the “lightest born twins in the world” according to the Guinness certification body.
