A third optional protocol was added in 2011. This enables children whose rights have been violated to complain directly to the UN Committee on the Rights of the Child.
Since it was adopted by the United Nations in November 1989, 194 countries have signed up to the UNCRC, with only two countries in the world still to ratify.
All countries that sign up to the UNCRC are bound by international law to ensure it is implemented. This is monitored by the Committee on the Rights of the Child
The UNCRC is also the only international human rights treaty to give non-governmental organisations (NGOs), like Save the Children, a direct role in overseeing its implementation, under Article 45a.

In fact, the world's very first declaration on child rights was written by Save the Children founder, Eglantyne Jebb, in 1923.
We've been there from the start, fighting for children's rights.
