Children's rights are the human rights of the children with particular attention to the rights of special protection and care afforded to minors. As minors by law children do not have autonomy or the right to make decisions on their own for themselves in any known jurisdiction of the world. Instead their adult caregivers, including parents, social workers, teachers, youth workers, and others, are vested with that authority, depending on the circumstances.[6] Some believe that this state of affairs gives children insufficient control over their own lives and causes them to be vulnerable.[7] Louis Althusser has gone so far as to describe this legal machinery, as it applies to children, as "repressive state apparatuses".[8]

Structures such as government policy have been held by some commentators to mask the ways adults abuse and exploit children, resulting in child poverty, lack of educational opportunities, and child labor. On this view, children are to be regarded as a minority grouptowards whom society needs to reconsider the way it behaves.

Children though smaller than adults in size and age are human beings and are individuals in their own right. they too have a a mind of their own with likes and dislikes. While adults' duty should be of guiding the children through the right path,  incidents of abuse towards children often occur. So children need the right to say no to what they dislike or be able to stand up for themselves. An individual irrespective of age or caste need the right protected by law which help him or her to defend themselves.
