A Plymouth mum has been found guilty of assaulting her four-month old son by slashing his feet with a razor blade.
Rachel Thompson, 40, was found guilty at the end of a week-long trial. The jury deliberated for two and a half hours.
Thompson, of Channel Park Avenue, Efford, aged 40, had denied deliberately assaulting the boy, claiming he had been injured in an accident.
Mum-of-three Thompson, has gbeen found guilty of child cruelty which took place between September 14 and September 18, 2011.
The baby was found to have two very similar wounds on each heel, with "partial thickness" skin loss measuring about 1.5cms by 0.75cms.
Thompson took the boy to hospital two days after she said the accident happened.
Medical staff immediately suspected that the wounds had been caused deliberately – partly because of the delay in taking him to the casualty department.
But her mother Angela Thompson, a former nurse, told the jury she had told her daughter on the night of the accident that the boy did not need to go to hospital.
She added that Thompson decided to take him two days later because the wounds looked worse.
The court heard Thompson had self-harmed previously and suffered from a personality disorder caused by childhood abuse in the home and bullying at school.
She has suffered from the eating disorder bulimia for most of her adult life, the court heard.
The jury has heard that the boy is still living at home with Thompson and partner Trevor Parkins. The couple also have a 15-month-old boy.
Thompson, a former nursing auxiliary and dental nurse, has a 22-year-old son from an earlier relationship.
Thompson has been released on bail and will be sentenced on November 7.
