Why is the declaration of the rights of a child smaller that the universal declaration of human rights?

The Declaration of the Rights of the Child is shorter than the Universal Declaration of Human Rights because it focuses specifically on the unique needs and protections of children, distilling key principles into concise, actionable rights. While the Universal Declaration encompasses a broad range of human rights applicable to all individuals, the children's declaration prioritizes issues like protection from exploitation and the right to education in a more targeted manner. This brevity reflects the need for clear, straightforward guidelines tailored to the vulnerabilities and developmental stages of children.
