The longest interval between the birth of twins is 90 days, in the case of Molly and Benjamin West, dizygotic (fraternal) twins born in Baltimore, Maryland, USA to parents Lesa and David West (all USA) on 1 January and 30 March 1996.
Molly was born three months premature on New Year's Day but doctors stopped Lesa's contractions in order that she could carry Benjamin for as long as possible.
