A mother who put her own blood in her daughter’s urine samples to try to show she was ill could face up to 10 years in jail.

The 31-year-old from Stevenage admitted wilfully assaulting, ill-treating and neglecting a child in a manner likely to cause suffering or injury when she appeared at Cambridge Crown Court on Monday. The court heard the girl spent a week at Stevenage’s Lister Hospital after her mother reported that she was ill with a high temperature and bloody urine.

Two days later, her mum took her to A&E, saying she was vomiting, had lower back pain and more blood in her urine.

The pair later went to Great Ormond Street Hospital kidney specialist Dr Kjell Tullus. A biopsy and uncontaminated blood tests were done there and were found to be clear. The woman was then arrested.

The case was adjourned for psychiatric reports. The woman will be sentenced on March 14.
