The mother of a disabled boy has met the head of Doncaster children's services to ask how her son died during a respite care break.
Seven-year-old Warren Jobling suffered from a rare genetic condition and died in April 2008.
A Serious Case Review into the way he died found he had a history of cardiac arrest and could have died at any time.
His parents dispute that finding and want the full case review made public as "questions remain unanswered".
Andrea Jobling met Chris Pratt, Doncaster Council's director of the children and young people's Service, to ask for more details about the investigation.
After the meeting on Wednesday she said she had been told the council would look into her concerns.
"There's nothing in the Serious Case Review that says where Warren was sleeping or where he should have been sleeping," she said.
"There are quite a lot of things that are missing out of the summary report."
Speaking earlier, Mr Pratt said: "I would want to consider any further information the family feels the council should be aware of."
The Joblings had earlier started legal action against the council over their son's death, but this has now been dropped.
Mrs Jobling said the family still visited Warren's grave on a daily basis.
She said they cannot move on until they get answers to their questions.
"I'm not going to give up even though I'm really stressed out all the time going over more paperwork.
"I want the closure so I want the right answers."
