More than 210,000 children are on waiting lists for health care and more than 25% have been in the queue for longer than a year.
It has also emerged there are massive variations depending on location.
While North Dublin has the biggest backlog with 2,400 children in the queue, just 10 kids are on a waiting list for speech and language therapy in Dun Laoghaire and none in Dublin South East.
Fianna Fail’s health spokesman Stephen Donnelly, who obtained the figures, said many kids are waiting for years, often for primary care supports such as speech and language therapy.
Others are languishing on lists for critical operations for conditions as serious as scoliosis – an agonising curvature of the spine.
Mr Donnelly added: “More and more parents have been contacting me about the inability to get care.
“This includes very sick children in need of urgent surgery. It includes those in urgent need of therapeutic supports like speech and language and occupational therapy.
“It includes children waiting for psychology, for diagnostic scans. I wanted to get a full picture of how bad things have got and the results are shocking – 215,000 children are waiting.
“Many are in pain, many are deteriorating. This is a damning indictment of this government’s failures. It is a dark stain on our country that this is happening.”
There are also more than 7,000 children and teenagers waiting to see a psychologist, jumping by almost a fifth in the last 12 months.
Mr Donnelly said: “This figure understates the full extent.
“Many hospitals don’t report waiting lists for different age groups, diagnostics waiting lists are not reported by age, and the figures don’t include a huge number of children waiting for oral health preventative interventions in primary schools.
“A €1billion overspend on a children’s hospital that only adds a handful of extra beds for children is about the extent of the Government’s work.
“These children and their families need solutions now.”
