Melbourne, Aug 15 : The daughter of Austrian incest fiend Josef Fritzl is teaching her kids how to play - because they don't know how.
Three of the seven kids, which Elisabeth bore Fritzl, spent all their lives in a dungeon in the basement of their home in Austria.
Doctors said they had no concept of enjoying themselves so Elisabeth, 42, is showing them how to swim, run and skate.
The family now lives in a house in the grounds of their psychiatric hospital.
Elisabeth spent 24 years in the dungeon in Amstetten where she was raped repeatedly by her father, now aged 74.
She had seven children, one of whom died days after birth.
Three were taken to live upstairs with Fritzl and his wife Rosemarie, 69.
The others Felix, 5, Kerstin, 19, and Stefan, 18, were kept in the cellar with their mother.
Now they play with her in the hospital grounds.
"It lifts your heart to hear these children playing and having so much fun after such a sad start in life. Their mother is a miracle worker," The Sun quoted a local resident, as saying.
Fritzl could get 15 years for rape and incest and a further 20 for slavery.
