A mentally ill Manchester woman who believed she was being persecuted by her neighbours suffocated her four-year-old daughter "out of love", a court has heard.
Chantelle Blake, 32, was made the subject of a hospital order on Tuesday after she pleaded guilty to manslaughter on the grounds of diminished responsibility at Manchester Crown Court.
The court heard she suffocated her daughter Kaiya with a pillow because she was suffering from "delusions and hallucinations".
Sentencing her, Mr Justice MacKay said: "The day you ended your daughter's life will, I am sure, be with you forever."
The judge said it was not the purpose of the court to punish Blake, as doctors on both sides agreed she was and is suffering from paranoid schizophrenia.
He said: "I fully accept that you did what you did out of your love for and concern for Kaiya."
Mr Justice MacKay said the defendant's "mental functions" were "abnormal" at the time.
"You were thinking in a distorted and deluded way, but you genuinely believed that you were acting to protect your daughter from harm by persons who wished her ill. You thought that because you were mentally ill at the time."
The court heard that Kaiya was found by police at their home in Garthorne Close, Moss Side, Manchester, on September 22 last year after the defendant turned up at A&E with a child's suitcase.
She had slashed her arms with a knife and told a nurse she had suffocated her daughter, the court heard.
