The 37-year-old woman from Queensland's Sunshine Coast made three films using her mobile phone showing her raping her youngest child and exposed her to other sexual activity "in response to repeated questions," The Sunshine Daily reported. Judge John Robertson said sexual offenses against children by their own mothers were "rare," describing the relationship between mother and child as "seminal in our society." He told the woman she had "no psychological or intellectual reason to explain this shocking behavior," as she had "a normal loving upbringing with parents and family who still support you." The court heard that the woman started seeing the father of her four children â€” 16 years her senior â€” when she was "virtually a child" at age 14. She had her first child at 16. She later began a cyber-sex relationship with a man and "became obsessed with sex." She would allow her daughter to view sexual videos the two sent to each other. "From the start you characterized your behavior as some form of bizarre sex education with the child which did not involve sexual gratification from you... You were obsessed with sex and your life was in chaos," Robertson reportedly said. He also said the mother, through her "selfish criminal conduct," had deprived her daughter of the right to "a wholesome and loving relationship with her mother."
