At 14, Jamie Rossookh was neither a boy or man - at least that's how his mother saw him.
The teenager, who has cerebral palsy and lives in the Black Country, was deemed too old by various agencies for child or school services.
However he was also too young to get help from organisations which provide help for adults, such as transport to and from hospital.
Andrew Sutton, who established the Foundation for Conductive Education in Birmingham, claims it is not an unusual situation. Apparently hundreds of children fall through the cracks between education, health and social services.
Now 18-years-old, Jamie is due to become social services' responsibility when he leaves Stourbridge College later this year. However, he is still waiting to hear details about this arrangement.
His mother Sue Rossookh, who lives in Wordsley, Stourbridge, said although the system was structured, children were left "in limbo" as agencies struggled to cope with the demand for services.
Mrs Rossookh, a part-time teacher, said: "I think many of these agencies are swamped and they're operating crises management so they never actually get on top of the situation.
"They just don't seem to have the resources or enough time to do any long term plans for these children.
"Joined up services is what should happen and I don't know why it doesn't. People have been talking about this for years and everyone seems keen on it, but it's still not happening."
The issue of joined-up services was initially raised after the death of Victoria Climbie and the public inquiry which criticised the lack of communication between various children's agencies.
Mr Sutton will talk about the issues when he addresses delegates at the Children's Trusts Conference in London on Thursday, which is cohosted by the National Institute of Conductive Education.
He believes conductive education would open doors for more children with cerebral palsy but many local education authorities are failing to fund access to such services.
"More than ten years on and it is still easier for a well-to-do family from overseas to come to this country and gain access to conductive education, than it is for most children living here," said Mr Sutton.
"With disabled children's services, hundreds of parents find their children get caught in the cracks between social services and education.
"People are going to have to start talking to each other and all relevant services must start communicating.
"Everyone who works with children will have to undergo professional training."
Children's Minister MP Margaret Hodge will give a keynote speech during the conference at the Institute of Directors, outlining the development of integrated services.
Mr Sutton plans to hold up the Foundation as an example of how integrated services can be provided for disabled children and their families.
He said: "Joined-up services are something we in conductive education have practised for many years but which is now being placed high on the Government's agenda.
"This is a rare chance for the conductive movement to show itself ahead of the field in practising what others simply preach," he said.
