QUIRKY WORLD ... Seeing double: Identical twins have twins (again)

USA: Kerri Bunker and Kelli Wall know a thing or two about twins. The two women are identical twins who already each have one set of twins. Now, they are getting ready to each have a second set of twins next spring.

“To have twins twice is incredible,” Wall said.

The Lindon, Utah, women both had their first set of fraternal twins after using in vitro fertilisation after they struggled to get pregnant. This summer, both found out they are having twins again. They are both due two weeks apart next spring.
