CINCINNATI (AP) - A set of rare "mono mono" twins photographed holding hands moments after they were born are home in time for Father's Day.

Jenna and Jillian Thistlethwaite were born May 9 sharing an amniotic sac and placenta at Akron General Medical Center in Ohio.

Hospital spokeswoman Amy Kilgore says the identical twins went home to Orrville in northeast Ohio on Saturday. They spent nearly a month in the neonatal intensive care unit.

They join their parents and big brother, 15-month-old Jaxon.

Their mother, Sarah Thistlethwaite, told The Associated Press on Sunday that the family is excited to be living under one roof after splitting time between home and the hospital for so long.

Doctors say the rare birth condition called monoamniotic, or "mono mono," occurs in about one of every 10,000 pregnancies.
