A troubled 11-year-old girl poisoned her mum twice by spiking her drinks with prescription drugs.
A court heard that on the first occasion the girl put five tablets in her mother's cup of coffee following a family row.
Her mum became ill and confronted her after the family dog also began vomiting – and the girl admitted what she had done.
But she struck again when they argued over her not wanting to play netball at school because she felt 'self-conscious in the changing room'.
The child, who cannot be named for legal reasons, slipped three anti-depressant mirtazapine tablets into a bottle of wine her mother and her partner were sharing.
The boyfriend did not drink the glass poured for him and the mum drank both, which made her nauseous and drowsy.
She questioned the child, who again owned up, magistrates at Fareham, Hampshire, were told. Police were called and the girl was taken into care.
She admitted unlawfully and maliciously administering a poison with intent to injure, aggrieve or annoy.
Defence solicitor Charlotte McLeod said the girl did not mean to kill her mother – just make her slightly ill.
The girl, now with foster parents, was said to have problems responding to discipline and had suffered domestic violence since the age of two – including being scrubbed in a bath until she was 'red raw' by her brutal dad. The family had also moved around a lot.
The child was angry about this and being told off was 'the last straw'.
Asked if she had anything to say, the girl sobbed: "I just want to go home."
Both mother and daughter are in a domestic violence programme after years of abuse by the father. The girl was placed under a youth supervision order.
