A man has admitted killing his 23-month-old son who died of a heroin overdose. Daniel Jones was found collapsed at his home last May.
His father Simon Jones (30) pleaded guilty to a charge of manslaughter at Wolverhampton Crown Court.
Daniel's mother Emma Bradburn (34) admitted a charge of causing the child's death.
Paramedics were called to the family's home on the morning of May 29 last year after Daniel could not be roused. The youngster later died in hospital.
Police found a small cannabis factory in the loft of the house.
Detective Inspector John Smith said: "Officers who initially visited the scene reported finding a clean and well-maintained house.
"Away from the areas where people may visit, the main bedroom was untidy and strewn with drug paraphernalia.
"It seems that Daniel became accustomed to living amongst these items and, tragically, consumed a quantity of heroin.
"We don't know exactly how the youngster came to ingest the illegal drug."
The pair will be sentenced in July.
