The United Nations Convention on the Rights of the Child (UNCRC) has 54 articles in all.
Articles 43-54 are about how adults and governments should work together to make sure all the children get all their rights.
A convention is an agreement between countries to obey the same law. When the government of a country ratifies a convention, that means it agrees to obey the law written down in that convention.
Knowing and understanding your responsibilities can be confusing at times and it is always a good idea to ask or help or look for explanations if you are not clear about any of your rights or responsibilities. As a citizen who has rights you need to be aware that others have the same rights and you therefore have responsibilities to respect others rights.
