What the law says...
Every person in the world has human rights, it doesn't matter who you are, where you live, who your parents are or what you do. Your human rights can never be taken away from you. Children (anyone under 18) also have children's rights because the international community understands that children are deserving of extra protection.
What are Children's Rights
The rights of the child (children's rights) are rights (freedoms you have) specifically for anyone under 18 years old. All children also are entitled to all the human rights, but children's rights focus on the special care and protection that children should be given.
In 1989 representatives from all the countries in the world agreed on a list of around 40 children's rights. They were all written in a document called the United Nations Convention on the Rights of the Child (the CRC). The CRC has been signed by almost all the countries in the world, no other international human rights law has been signed by more countries!
