James Taylor's body was discovered at the house in New Ash Green
The mother of an 11-year-old boy who was found drowned at his home in Kent has admitted his manslaughter.
James Taylor died at Knights Croft, New Ash Green, near Dartford, on 2 December.
Jennifer Taylor, 45, pleaded guilty to manslaughter on the grounds of diminished responsibility and will be sentenced on 20 June.
At Maidstone Crown Court, Judge Andrew Patience QC said he was satisfied she was suffering from a mental disorder.
The case was adjourned to allow psychiatric reports to be carried out and an interim hospital order was imposed by Judge Patience under Section 38 of the Mental Health Act to make sure Taylor remained in custody.
Two post-mortem examinations revealed James had died from drowning. Traces of drugs were also found in his body.
Emergency services discovered his body at the home in Knight's Croft in the early hours of 2 December.
Taylor was also found at the house and taken to hospital where she was described as being in a critical but stable condition. She was arrested after being discharged nearly a week later.
At the time of the incident neighbours described James as a "lovely boy" who was always playing outside and his mother as someone who kept to "herself to herself".
James was a pupil at Wilmington Grammar School for Boys in Common Lane, near Dartford.
Following his death head teacher Fiona Cottam released a statement to parents in which she said James had shown great academic promise.
