The number of complaints to the Ombudsman for Children increased by 34% last year.
It shows that concerns about the provision of education and healthcare made up the majority of complaints received.
Emily Logan published her annual report today.
The Ombudsman for Children dealt with over 1,200 complaints in 2010.
Three quarters of those were made by parents on behalf of their children.
Most complaints in relation to education were about the actions of teachers or school principals and the manner in which they interacted with pupils.
Complaints about the adequacy of healthcare are common.
The report also identifies problems in relation to geographical variations in Health Service Executive provision of services, such as psychiatry, speech and language therapy and physiotherapy.
Ms Logan said there is still too much bureaucracy surrounding decisions that impact on children.
She said much of this could be simply addressed by a change in administrative culture.
Traveller's priest urges Govt to reconsider cuts
The priest of the country's only Parish of Travelling People has urged the Government to seriously reconsider cuts to resource teachers for Traveller children in the wake of concern expressed by the Ombudsman for Children.
Fr Derek Farrell, whose parish first tried to highlight this issue over two months ago, said they had no positive response to their pleas for a reversal to, or postponement of, the cuts.
Today, the parish said they hoped the voice of Emily Logan, who also spoke out on behalf of Traveller children, would help lead to a reversal of this decision.
Fr Farrell said, clearly the Ombudsman recognises that these blunt cuts will, in effect, mean Traveller children will be more disadvantaged educationally than before.
Of the 1,200 resource posts that are due to be cut by the end of this month, almost 800 are in Traveller Education at primary and post-primary level.
‘As we said last March this is clearly an issue of fairness and justice,’ said Fr Farrell.
‘How is it possible that two thirds of the cutbacks in the area of Resource and Visiting Teachers are targeted at Traveller children? These include many children who have benefitted enormously from resource teaching to date, but who are at serious risk of dropping back or dropping out of education if that extra help is pulled from them.’
