Janelle Perry, a grandmother from Queensland, Australia, has given birth to naturally conceived triplet boys in a 'one-in-a-million' delivery at Brisbane's Mater Mothers' Hospital.

Janelle and husband Robert's tiny trio - Cooper, Kyle and Jordan - were born at 34 weeks' gestation by caesarean section last week.

Doctors are "99.9 percent certain" the boys are identical. Perry, who turns 47 next week, now has eight children. She said she is adamant that is enough.Perry has four children in their 20s from a previous marriage, a daughter, Rebecca, 4, with Robert, and two grandchildren.

The Perrys, of Logan, south of Brisbane, sold all their baby things last October after trying unsuccessfully for two years to have more children.
