SALT LAKE CITY (AP) -- Identical twin sisters from Utah each recently gave birth to identical twins -- again.
Kerri Bunker and Kelli Wall delivered twins within weeks of each other at a hospital in Orem, south of Salt Lake City. Years ago, they gave birth to their first sets of twins, now 4- and 5-year-olds, at the same hospital a few months apart.
Bunker's newest twins arrived Feb. 13. Wall's youngest twins were born about three weeks earlier.
Ryan White, spokesman for Timpanogos Regional Hospital, says some of the twins were conceived through in vitro fertilization.
The 36-year-old women say they aren't just sisters but best friends, neighbors and co-workers. They say all nine kids will grow up together.
Bunker also has a 2-year-old child.
