Some parents of children with special educational needs (SEN) meet "brick wall after brick wall" when seeking school support, a committee has heard.
The Northern Ireland Affairs Committee is holding an inquiry into the funding and delivery of public services.
Parents from the SEN Reform NI group appeared before MPs on Wednesday.
Their evidence included a claim that a parent has to regularly go to a school to change their child's nappy in person due to a lack of support in school.
There were significant pressures on suitable school places for children with SEN this year.
That meant that hundreds of children had to wait until the summer holidays before their school place could be confirmed.
Some parents held a protest at Stormont about the situation they and their children were facing.
As well as those waiting for a place, almost 2,500 children were in the statementing process over the summer according to the Education Authority (EA).
A statement is a legal document that sets out a child's needs and the support they should have in school.
